firewall.

Subject: BGP OSPF question
Hi all, I have a unique scenario where we need to establish a dynamic
routing protocol over layer 3 firewalls. With EBGP we can do multihop
to
skip the firewall, but with other protocols such os ospf, eigrp, rip, is
there any option to establish a neighbor without using GRE to tunnel
over
the firewall? Assume in all cases the firewall cannot participate in
any
routing protocol.
Is there a way to do multihop with ibgp? Is there a hop count limit to
multihop?
THanks much.
