Can a USG 110 run without local WAN access?
We have 2 sites with USG110 and cable modems. We added a third site USG110 and put a fiber backbone between all 3 sites using the DMZ ports. We are using policy routes at the new site to send all traffic to one of the existing sites over IPSec VPN. We are using 2 policy routes, 1 for all and 1 for ZyXel to send all traffic next hop to the VPN tunnel. LAN internet access at the new site works fine. The new site 110 cant get time info from internet or get version upgrade information. Is there any way to get the internal functions of the USG110 to use something other than the WAN ports to get its internet access.
