I have taken over a system of Avaya phones connected to our network through a VPN tunnel. All of the first 8 are working fine, but when I try to add a 9th one, I am having issues. Here is the layout:
All Avaya 4610SW phones are connected to a Netgear FVS114 Prosafe VPN Firewall, which connects over the outside cloud to our Cisco 515E PIX. Even though the Netgear shows the connection of the IKE SA to be SA_MATURE, I cannot ping either the Avaya PBX or TFTP servers, even though the Netgear is setup exactly as the other 8, which can ping the PBX and TFTP. I am not near the limit of the number of connections for either the PIX (it allows 2000), nor the TFTP or PBX, which will allow 30.
At this point I am trying to figure out why I cannot ping the PBX or TFTP with the tunnel up. That seems to be holding up the whole process. Do you have any ideas?
