Re: [LARTC] SIP, NAT, and load balancing problems

[François Delawarde <fdelawarde@wirelessmundi.com>]

I have ip_nat_sip compiled in the kernel (and not as a module). Is that 
an issue?
Could you give me an example of how I could do using CONNMARK and fwmark 
based routing if I have an outgoing RTP flow bound to the wrong interface?
Thanks a lot,
François.
