l2tp vpn passthrough

TarekHalloun over 5 years ago

hello awesome people

i need a quick support on this one , i have a vpn server on my router behind the sophos xg running v18 - my public ip and internet is on the XG

i need to forward the l2tp to my router but i am failing to do it on the new v18

can you just point me to it ? should i just give access to Lan/local router with service l2tp ?

thank you

Hi TarekHalloun

Thank you for reaching out to the Community!

You would have to configure the DNAT rule to forward ports required for the L2TP to your internal router.

Check out the following video for more info: Sophos XG Firewall (v18): NAT Enhancements.

Thanks,

Hi TarekHalloun

If you only have one WAN interface, you could only use L2TP either on the XG firewall or on your internal router with the help of the DNAT rule. The other option would be to use a different port for L2TP on your internal router or the XG firewall.

Hi TarekHalloun

Please open the L2TP configuration on the firewall and find the Local Port, by default it is 1701. Unfortunately, I do not have any documentation on how you could change the L2TP port on Windows.
