Yupp, i thought about that too.
I tried a number of residential routers, but
all of them did some sort of coned NAT. Who could
name symmetric NATs?
Linux NAT is symmetric and is quite common with small
businesses. We use the
RTPProxy in these cases.
freeBSD is per default symetric too. There is a small patch though which makes
it into a full cone NAT.
We have currently cisco ATA's 186 and the grandstream working with the
current CVS release and the NAT support/RTP Proxy.
Great software btw!
