we could define two same dial-peer (only ip address is different) to create redundancy if the 1st ip address is not responding.
if we apply max-conn=2 to each dial-peer, the incoming connection will switch to the 2nd dial-peer if the max-conn for 1st dial-peer is reached. That is, 4 max connections are allowed.
we want to limit the max-connection to 2 but we also want to have backup ip addresses.
