I have a RUT955 connected to an L2TP server running on a Mikrotik router. The connection works, the RUT gets assigned a virtual IP (172.16.8.87 in this case) and it can access my HQ router/L2TP server (10.188.0.1), but for some reason it can't access the rest of the HQ network (10.188.0.0/24). From the HQ network, I can't access anything on the remote side – I can't get to the router neither by its LAN IP (10.188.2.1) or by its virtual IP. I have added firewall zone rules to allow traffic between the L2TP IF an LAN/WAN. I tried turning off the firewall completely, which made no difference.
I can ping the RUT from the Mikrotik, but I can not ping the RUT from a computer in the HQ network.
