VoIP and SSH

[Andrew Falanga]

Hi,

I don't understand this one and I'm hoping someone here might know.  My 
father's router wasn't forwarding connection requests for any port that we'd 
configured for sshd to listen on.  After changing out his linksys router and 
his Cable MODEM (the company said it was a very old modem), the problem was 
still present.  Oddly enough, if he unplugs his VoIP box from his network, 
all this problem goes away and connection requests over ssh and port 22 are 
forwarded fine.  With the VoIP box present, it doesn't work.

Neither the FreeBSD machine or the VoIP box share IPs, but it doesn't work 
with the VoIP in the network.  Any ideas?
