[sr-dev] 3.1 crashes in topoh on receiving 180 message

  Hello,

it confuses some topoh processing, because the mask_ip should be 
different than local ip -- can you try with 127.0.0.1 or some private 
address (e.g., 10.10.10.10) in mask_ip?

It should not crash anyhow, so I will fix it - one option is to check 
that mask ip is not used as listen ip, I will think about and find a 
solution. It is not specific to 3.1, is also in previous version.

Thanks,
Daniel
