With abandoned Metarouter this seems to be a nice feature request.
And I also I'm accepting esp and udp500,4500 on input.
Sorry for necrobump, but same problem here. I still have no clue how to solve it.Thank for your reply, i have this rule, and i can ping the remote network from the local network, example: 192.168.255.30 to 192.168.1.51 but i can not ping the host 192.168.1.51 from terminal of router RB450.
