Active ftp, and passive ftp are different in the way how server works in the process of file transfer. This different impact in how you configure the firewall, if any.
Active FTP
In active ftp, client connect from random port (>1023), to ftp server port 21. Then, in data transfer, server send data from port 20. In firewall setting, you to do the following thing.
In client side firewall, you need to open connection from port 20.
In server side, you need open connection to port 21 from port > 1023, and open connection from port 20 to port > 1023.
Passive FTP
In passive ftp, the first stage is the same with active ftp. The different is in data transfer. In passive ftp, the client initiates both connections to the server.

Combine with premium blogger templates, adsense ready templates can be a wonderful templates. I found some premium blogger templates with adsense ready widget and banner. Some of theme are Arthemia, and Bloggermint. These two templates have adsense banner ready at top of blog, and adsense widget ready.
To make these templates SEO friendly, I also add function to add meta description on each of post, change title tags using post title, and also remove blog name from post title tags. Every post title also use H1 tags. These templates are also added with related posts on every below post content, to increase pageviews of your blog.

Blogging is started by choosing a template. Many free templates from internet, from simple to premium templates. Premium templates generally have nice looks, and more choices. Not only have nice looks, a good template also need to have SEO friendly.
SEO friendly comes from title tags, meta description, and post title. These premium templates have two column, tab menu, nice looks, adsense, and banner ready. To have more SEO friendly functionality, I added title tags using posting, meta tags on each posting using post title. To make it more relevant with search engine, and have more SEO friendly, I also change post title to use H1. Also I added related posts function placed below post content so your reader can be directed to others post on your blog.
Related posts can help your have more pageviews, especially if it's placed below post content, so at the end of the post, if readers see others post related with already read post, it gives probability to read.
You need to modify home page meta description and meta keyword setting to match with your blog. Just go to Design ---> Edit HTML, find code like this,
<meta content='Get SEO friendly premium blogger templates, blogging tips to improve SEO, and adsense revenue.' name='description'/>
<meta content='seo friendly premium blogger templates, premium blogger templates, adsense ready blogger template, adsense in blogger template, premium blogger template, improve seo, adsense revenue, infolinks optimization, wordpress theme' name='keywords'/>
Change with your own blog meta description and keyword. You no need to change meta description setting for every blogger post, because it's automatically inserted using post title.

Internet is a set of Autonomous Systems (AS) that interconnect each other. Autonomous System is a network under the same administration. Autonomous System use Exterior Gateway Protocol(EGP) to connect and exchange information each other. Information in this term is routing information. Today, BGP is the only EGP used in the internet. Comapred with IGP that only used inside AS, BGP can be used outside and inside AS (IBGP). Current version is BGP-4. BGP is defined in RFC-1771. BGP using port 179 TCP to connect.
BGP is classified as distance vector routing protocol, but with some enhancement called attributes.
BGP characteristics:
Distance vector routing protocol
Keep alternative routes
Loop free routing
When a connection established initially between AS's, BGP speakers exchange the whole table, but then their only send only update. BGP update consist of prefix length, network prefix, and attributes, such as as-path, next-hop, origin, local-preference, med, etc. AS path is a series of AS that need to be traversed to reach a destination or prefix.
BGP consist of IBGP and EBGP. IBGP neighbor is in inside AS, and require fully meshed. EBPG neighbor is in different AS, and must be reachable, either it's directly connected or multihop.
BGP Updates
BGP updates characteristic is different between IBGP and EBGP. When a router receives an update from external neighbor, it will send to all internal neighbor. When a router receives update from internal neighbor, it will not send back to others internal neighbor. This mechanism is used as loop avoidance. As the consequence, IBGP need full mesh between all routers in the AS. Later, we will discuss about route reflector that will break this rule. Router reflector is used to overcome need of full mesh connection.
BGP Path Selection Algorithm
BGP uses complex mechanism to choose what routes is the best.
Do not consider path if no route to next hop
Do not consider iBGP path if not synch
Highest weight (local to router)
Highest local preference (global within AS)
Prefer locally originated route
Shortest AS path
Lowest origin code
IGP < EGP < incomplete
Lowest Multi-Exit Discriminator (MED)
If bgp deterministic-med, order the paths before comparing
If bgp always-compare-med, then compare for all paths otherwise MED only considered if paths are from the same AS (default)
Prefer eBGP path over iBGP path
Path with lowest IGP metric to next-hop
For eBGP paths:
If multipath is enabled, install N parallel paths in forwarding table
If router-id is the same, go to next step If router-id is not the same, select the oldest path
Lowest router-id (originator-id for reflected routes)
Shortest cluster-list
Client must be aware of Route Reflector attributes
To create access on Cisco router that only allow outgoing tcp connection, and block all incoming traffic, except traffic initiated by incoming users, you need to allow established connection initiated by inside host. Thos post will gives example for creating access list that only allow connection initiated by inside host or itjust allow TCP sync from inside host. In other word, this access list will block all TCP sync traffic from outside network.
ip access-list extended OUTGOING-ONLY permit tcp any any gt 1023 established
permit tcp any eq ftp-data any
permit udp any eq 53 any
As normal TCP sync request is initiated from port greater than 1023, in this access list we just only permit traffic established from port greater than 1023. To allow FTP traffic, ftp data port (TCP 20) from FTP server must be allowed. Also UDP 53 port need to be allowed cause DNS server use port 53 UDP to reply data.
Place this access-list in outgoing interface to inside direction
SEO can be started by choosing a SEO friendly template. Basic blogger templates are usually have no SEO friendly. Beside Wordpress, Blogger is a free blog platform that majority used by world blogger. It has simple template, and easy to modify. Basically, to make it more SEO friendly, a blogger template must have title tags that match with title post, meta description that describe post content, and H1 for title to make it more relevant with search engine. Most of basic blogger template have no SEO friendly setting, and need to modify it to have SEO friendly.
SEO friendly setting need to be modify in blogger template are:
1. Title tags
Some of blogger template have title tags like this:
Blog Title - Post Title
This setting makes post title less significant than blog title, so the title tags can be irrelevant with post content in the view of search engine. Blogger template need to be modified to change title tags using post title.
2. Add meta description tags
By default, basic blogger template setting have no meta tags setting. We need to modify template so it have meta tags for main homepage, and add different meta tags automatically for every post. Different meta tags for every post can be generated from post title. Meta description give a description about the content of your blog. Most of search engine use meta description to find relevant content.
3. Post tag
Use H1 for post title to make your posting more relevant with search engine, and SEO friendly.
Infolinks has two type onf in-text-link ad, double and single dotted line. After tried using two types of Infolinks In Text Ads, double line and single dotted line, I choose to use single dotted line. Here is the reason.
Infolinks recommend double line, but in facts, based on my experience, performance or CTR of single dotted line is better than double line. I think that this is caused by appearance of single dotted line is more similar as hyperlink or regular link to a page or website than in text ads, and seems as the part of whole content. Try your Infolinks experience by yourself, by join using this link, and start to get revenue.
Infolinks provide two types of their in text ads, double line, and single dotted line. Infolinsk suggest to use double line ofr their in text ads type. They state that double line will have better performance.
When first time I joined Infolinks, I used double line. Performance is very poor, in the context of number of clicks. Then I tried to use single dotted line. Compare with double line, performance is far better. I think, single dotted line is appear as part of content than as in text ads. This gives more possibility to click than as it appear as in text ads.
