is there a patch for netfilter regarding the SIP protocol (for telephony
in VOIP).
It seems there is, but, I can not find it.
Any suggestions ?
What do you want the patch to do? What feature are you missing?

(You know about things like CONFIG_IP_NF_SIP? If it's a NAT issue,
recent kernels have SIP-aware stuff, though I think the earlier attempts
were a bit flaky.)

Great !
This effectively concerns the NAT issue. How make a PC behind a linux
firewall with MASQUERADING working with X-lite ?
I'll dig this !
thanks a lot.

The X-lite and many other good SIP clients/servers can also use STUN for
traversing UDP datagrams/packets over NAT.

My goal is to make X-lite (under windows, on a PC behind the firewall)
be able to work through the linux firewall, with no modification (as
possible) on the windows client.
Would STUN help for this ?
I must admit I didn't know STUN.
