Lab route protocols alternatives

[mohammedalrawiib]

Hello everybody 

I have a lab where some hosts are connected to the firewall that firewall is connected to a router i wanna ping the loobback interface on the router from hosts (ping from hosts to the loopback in the router) the idea of the lab is ping and make it reachable to the hosts without the need of using routing protocols or default route keep in mind ofc there is a switch before firewall then firewall is connected to the router this is the topology of the lab.

Many thanks in advance

Hello @mohammedalrawiib ,

>> the idea of the lab is ping and make it reachable to the hosts without the need of using routing protocols or default route 

then you can use specific static routes on the Firewall with destination the router loopback address on the router with destination the internal LAN subnet on the FW.

This is true if the LAN switch is L2 only otherwise it needs to be configured with static routes as it is explained above.

Hope to help

Giuseppe

Hello
If the router is on the "outside" of the fw then you may need to apply a fw rule to allow icmp echo, echo-reply, especially if you wish to initiate pings from the rtr towards the hosts
