for infrastructure traffic <->routerA<->FW<->routerB, and if both router using eigrp, except ask FW to open a hole for eigrp communication though, can I use eigrp tunnel?
I am a little confused, if I do use the eigrp tunnel, will it tunnel all traffic bypass the Firewall? can I only make turnnel with the routing protocol eigrp traffic only, so all user traffic will get firewall checked?
If it is correct method to use, please advice me an example of configuration.
Any comment will be appreciated
Thanks in advance
in general if you have a firewall in between
you can do one of the following:
- use a gre tunnel to bypass the firewall and make sure the firewall permit gre traffic
- let the firewall participate in the routing
- use the firewall in transparent mode
can you post your diagram of the network to understand it in more detail
