Using VPN server for multiple routers as Site to Site VPN
Posted: Mon May 23, 2022 5:45 pm
Hello,
I have 3 routers (LAN block 192.168.11.0/24, 192.168.12.0/24, 192.168.13.0/24) and they can get IP from VPN server (172.17.10.0/24) . Connection type is L2TP/IPSec but can't route traffic between them. I tried following steps
1- Enabled DHCP server with gateway, clients have IP from server and added static route to SecureNAT (192.168.11.0/255.255.255.0/172.17.10.11, 192.168.12.0/255.255.255.0/172.17.10.12, 192.168.13.0/255.255.255.0/172.17.10.13)
2- Enabled DHCP server without gateway address, clients have IP from server and added static route same as above
3- While DHCP server is enabled gave static IP to clients from device settings but couldn't give gateway, added static route same as above
4- Disabled DHCP server and gave static IP but VPN server would reject connection even there was no security policy like enforce DHCP IP pool...
5- When IP is taken from DHCP server, default gateway shows 1.0.0.1 but there is nothing like this in configuration
6- While DHCP server is enabled gave static IP to clients from device settings, removed static route from SecureNAT, and gave static routes from routers like above
7- Just for try, I connected all 3 routers to a router and routed traffic between them without any issues but I would like to use SoftEther for this
Can't think anything about more what to do
Thank you for help
