RE: OSPF on Firewall

["Ran Nahmias" <rnahmias () earthlink net>]

Shimon,

Most advanced firewalls will support "OSPF pass through". If you have only
two routers, it's even fairly safe as you can open the pass through for the
specific IPs of both routers.

Subject: [fw-wiz] OSPF on Firewall


Lets say that I have two routers (on an internal network) that talk OSPF
between them.

Now I have to insert a firewall in-between the two routers.

I am led to believe (by the Communications people I work with) that there is
no other option but to install OSPF on the firewall, which doesn't make me
feel easy about the solution.

Is it true that there is no other way around this problem?

TIA,
