We have a Sonicwall TZ210 as our firewall and a UC560 behind the Sonicwall.
Issue - I can't ping the UC 560 data VLan from the sonicwall. The UC 560 can ping the sonicwall. The sonicwall lan is plugged into the UC's WAN port
Sonicwall - 10.0.102.1
UC Device 10.0.102.250
Vlan Data - 192.168.15.1
I have tried changing the IP of the sonicwall to vlan subnet - 192.168.15.2 and moved from the UC - WAN port to the PC port - still can ping the vlan from the Sonicwall.
Any suggestions what to try next?
I'm not sure of the reason why, but have you considered replacing the firewall entirely with the UC500 ?
I did in some case and the customers where really happy especially they like the Cisco VPN cleint being much faster and realiable than the other product, also allowing to run Cisco softphone.
