Transparent Bridging Firewall's

By simo7111 ·
I am very interested in learning more about Transparent Bridging Firewall's. I am unable to find any articles/journals with information and would be glad if anyone could give me a good lead. I'd like to write a journal article and this would help!

Thanks!

install, test, make your own conclusions and then write them nice.

Let us know what you came up with.

Transparent bridging does not appear to offer all the benefits of layer-3 firewalls, such as the ability to create DMZs and ACLs to segment traffic and anti-spoofing preventions, creating segments with different security levels, protocol inspections such as the "fixup" process on PIX...and maybe a few others I can't think of. The article provided above talks about reasons to use bridging firewalls is becuase layer-3 firewalls are so (paraphrasing here) 'hard to put it.' THat seems to be a very lame excuse. There are a lot of benefits to segmenting and firewalling at the same time: Can you say NAT? NAT/PAT is what keeps the majority of the Internet losers out of your network, and this is a major advantage over bridging firewalls.
