IP changing back and forth between VPN Server and ISP Server

SemiLucas

Hallo,

I have configured a easy connection to a vpn server using wan connection thru 2ltp. 

Now wehn I check my IP online it keeps changing between the one the VPN Server provide me and the one from my ISP, back and forth.

Any idea where this could come from?

Thanks

Can you collect the  following information to check?

1)     Show USG policy route

                  => SSH connect to USG and type CLI.

                  => Router# show policy-route

2)     Show Windows routing table before L2TP connect to USG

                 => In Windows command prompt: use "route print -4" command to share the dumped information to us

3)     Show Windows routing table after L2TP connect to USG

                 => In Windows cmd prompt, use route print -4 to dump the message again

Thank you, I hope it helps.

To be clear, I use a WAN coonection over l2tp

Hi @SemiLucas,
I see, so the USG is l2tp client, instead of l2tp server role. can you send me your configuration file via private message.
