[Asterisk-Users] IAX with shaw cable not going through

[John Cianfarani]

Rogers does the same thing all you need to do is a DHCP release (or the
equivalent in your FW).  I had similar issues (not asterisk related)
since I have a pix fw and it has no option to do a dhcp release.

I've boot my asterisk backup server to  ADSL and everything is working
FWD, VoipJet.

Short story: The only thing I've done differently is I've spoofed MAC
address on the firewall on an external port - eth0 to get the same IP
address from Shaw, but I don't see how that could make a difference.

Long Story: Shaw has those new Cable Modem - Motorola SURFboard SB5100
that once configured to an IP address with one firewall it will retain
that MAC address of that first firewall for about 4-hours.  When I first
experimented that Cable Modem I've connected my backup firewall and the
Modem retained that MAC address.
So in order to connect the second firewall and get the same IP address,
I need to spoof the MAC address of the first firewall or wait 4-hours.
So I went with the second solution but I don't see how that could make a
difference, the only way to tell is to wait 4-hours to remove the spoof
MAC address from the firewall.
