Microsoft RRAS behind XG135 (VPN Pass-through) not working

Hi,

 

I'm trying to setup a M$ RRAS connection to a server on the LAN behind a XG135 without success!

Have setup a Business application rule using the DNAT template as follows:

after having read this: https://www.reddit.com/r/sophos/comments/7gphny/vpn_passthrough/

but when I try to connect using the M$ vpn client from a machine via the WAN the connection fails.

Have I missed something?

Any help or advice or next steps to resolve appreciated.

BR.

  • On XG Virtual 17.5 this does not work. Tested on RRAS first made sure it was working then put XG in front.

    First of all you do NOT need ESP, GRE or port 1723 for L2VPN, just 500, 4500 and 1701 all UDP.

    service IKE covers the first 2 ports and l2tp the third. But first rule did not work. Then I  made separate rules for each service and BOOM working.

    port 1723 is for PPTP only and may require GRE so i would think you swap out the 2 services but i did not test.
