I have a central site with a Zyxel Zywall 310 and a remote site with a Zyxel USG 20w. I also have a working IPsec VPN between the two sites.
LAN1 of the remote site can access Server1 on
LAN1 of the central site, but not Server2 on
VLAN4 of the central site.
What rules would I need to add to allow PCs at the remote site (behind the USG 20w) to access Server2 on
VLAN4 at the central site (behind the Zywall 310)?
Here's what the network looks like:
I suspect the solution may involve either Policy or Static Route rules (I currently have none set, though I've tinkered with them a bit, but was unable to get anything working).
