Nethserver is the gateway.
What we have is a Nethserver as a VM with a WAN interface going to a network which we do not care about. and then a host only network on a LAN interface which is where the servers are. Those servers connect to the internet through that Nethserver.
Problem is those same servers cant ping the servers on the other side of the VPN (or even the tunnel IP) nor can Nethserver. so a weird issue on the server side as I have the following
10.255.6.0/24 on the server side LAN
10.0.6.0/24 on the client side LAN
172.16.16.0/24 as the tunnel network
From my client side I can ping the tunnel IP of the nethserver. access those servers and even log into nethserver GUI and stuff. but on the other side I can not ping my client nethserver at all or even the servers. so how is the VPN only working one way
I have allow all source to allow all destination on both nethservers as neither are setup as the main router in either network.
I have created a static route on the cisco router on the client side network but seeing as the nethserver cant ping my client network from the server side I don’t think that will help. and the server side is all self contained with the nethserver as a default gateway for the servers
I cant set a static route on the main server side router as its not a flashy unit (temporary off the shelf netgear) but I cant see how that would help as I cant do the pings inside the nethserver GUI to my client nethserver
