[OpenSIPS-Devel] eyeBeam NAT ping packets

[Ovidiu Sas]

I forgot to mention in my previous e-mail that those ping packets are
over UDP, which seems like a bug in eyeBeam.
Anyway, the end result is that opensips logs are polluted.
Over TCP, it seems that those packets are properly handled by opensips.
It's UDP that is having issues.

Ovidiu Sas
