unable to initialize a WAN link

Actually it works if I reboot the XG for about 6 hours. Then goes down and no way to reinitialize. I know the wan works as we had it on a different firewall for a year.

Uhm...

Pay attention with ARP table. Make sure to clean the switch mac-address table. From XG console:

system diagnostics utilities arp

and check that the WAN router is there with the correct IP -- MAC Address.

Do the same on WAN router/switch between them (if there is one). WAN router, even after a reboot, retains mac-addresses and they can require even 48 hours before purging old mac-addresses. Call your ISP in that case.

Thanks. I will look into that.
