SIP Passthrough / NAT helper

[Michael Schäfer]

Hi,

is it possible to change the ports used for the SIP passthrough and the NAT helper? It seems to be fixed to 5060 and the only way to get it working on another port is to manually unload nf_conntrack_sip and nf_nat_sip, then modprobe both of them with the ports= parameter. But I can't find a way to get that persistent, i.e. /etc/modules.conf or something like that.

Anyone got a suggestion?

Put your commands in a firewall-start script.

That might work, but it has the disadvantage that I have to reload the modules. It would be preferable to have a way to establish permanent mod options, as there doesn't seem to be a way to change the port after loading the module using /proc or a syscall. But I'll give it a try.
