We have a 3com V3000 phone system. Our office network is DCHP'ed by the fire wall and has a .1.1 domain. The RED hardware has a .4.1 domain and DCHP's locally.
We have a 3com 3102 handset that we configured in the office by auto discovery. We took it to the remote office and get the error message "wait for NCP M". System is set up for IP on the Fly.
We have the RED device set for "any" communication each direction with the "in office" system.
The phone is the only thing connected to the VPN device. Angry IP reports no ip address for any of the handsets when scanned from the .1.1 or .4.1 domain. The NBX Telephone configuration>Telephones>IP settings is not reporting an address for the remote phone. I tried forcing setting an IP address, subnet and gateway at the correct domain to the hand set, but this did not work either.
The odd thing is if I plug in my laptop in the RED that has a soft phone installed, it works fine. SBS communicates fine too.
Here is a traffic monitor that is going on at the VPN device with only the handset connected:
Proto Source IP Port Destination IP Port Bytes in Pkt in Bytes out Pkt out
udp 0.0.0.0 68 255.255.255.255 67 1146 3 0 0
icmp 192.168.4.1 - 192.168.4.254 - 48 1 0 0 (I am guessing this is the hand set)
Something that is troubling, is the udp 0.0.0.0 response on the packet monitor. Its always paired with the vpn device, 1628 times a day.
Another thing is I cant ping any of the known devices, laptop or handset on the RED from the office. Is this normal?
Any recommendations?
thanks in advance.
