using eigrp between two routers over a firewall

[admin_2]

I want to use dynamic routing (eigrp) over a Firewall. The Fw don't speak eigrp. Do you have any idea and maybe

some usefull links?

As the firewall does not pass

multicast traffic that is used by EIGRP,

you will need to configure a GRE tunnel

between the two routers. Please see the
