How to configure modem/router so that all VPN traffic pass through it. there is no VPN option tab on the Modem/router. please see the files attached to help you.
Thanks in advance
If there is no access rules/firewall configured on the modem/router, the VPN traffic should pass through just fine.
Are you configuring any NATing on the modem/router? Also, is that site to site ipsec vpn?
Thanks for your answer
The modem is beawan, there is a nat config inside the modem just to forward ssh port to the local network, yes site to site
In that case, you would also need to configure port forward for the IPSec VPN traffic.
Do you know if NAT-T is enabled on the IPSec VPN tunnel? if yes, then you would need to port forward the following:
UDP/500 and UDP/4500
Otherwise, if your ipsec vpn is using other ports, you would need to port forward that accordingly.
If NAT-T is not enabled, then you would need to configure static NAT for your VPN server ip address.
