I updated to 7.505 last night and one of my internal SIP clients is no longer keeping a connection open according to the external sip server. The packet filter is now dropping all the traffic. The other sip client is working fine.
Example -
10:27:57 Default DROP UDP xx.xx.xx.xx : 5060 → yy.yy.yy.yy : 5065 len=521 ttl=51 tos=0x00
Where xx is the address of the sip server, yy is the address of the astaro box.
A few questions -
- The client is registering port 5065 rather then 5060. Does that bypass the automatic SIP handling?
- Did anything change w/ regard to SIP in the 7.505 build?
- Do I need to add a DNAT/SNAT rule for this case?
I looked at the historical logs and I don't see these packets getting dropped before the migration to 7.505 so I think this is something new. Or it is now identifying a bad configuration that I have had in place for a while.
Thanks!
