[Serusers] NAT ping and consumer router

[Richard]

Hi,

I hate to argue with a guru whose product benefits us a lot... :)

Anyway, if you can program your ALG and fix any problem one might have, why
isn't it a better choice? Some routers give away source code. They are linux
kernel 2.4 with netfilter. It tracks various protocols besides SIP. I
checked their code, it is no different than the methods used in nathelper,
mangle the ip address embedded in SIP message. I'd think that it is
definitely better than reducing registration interval, using voice proxy and
sending pings.

Btw, I don't think that one can find out a lot consumer based router working
with NAT ping. 80% of products in the market are based on linux
kernel/netfilter which only refreshes binding with outbound traffic and the
timer for binding in 30 seconds by default.

Thanks,
Richard

If people ask me how to make SIP/NAT stable right now, regardless of sanity,
my preference is to find a good UAC and stick to it. (I have to admit
I don't have a specific recommednations -- the capabilities change rapidly
fimrware by firmware in a pace I can't follow.) Configure SER to help
by reducing registration intervals, using a voice proxy, sending pings.
