L2TP site (2xLAN) to site (2XLAN) ping timeout

Fri Mar 18, 2022 8:24 pm

Hello,
I'm a new user and I'm having trouble setting up routing for my L2TP connection.
This is a two-site VPN connection scheme

The L2TP server configuration looks like this:

The client configuration looks like this:

The connection between network:
- B (192.168.2.0/24) and D (192.168.3.0/24) is working fine, the ping is working both ways,
- B (192.168.2.0/24) and A (192.168.22.0/29) is working fine, the ping is working both ways
- D (192.168.3.0/24) and C (192.168.33.0/30) is working fine, the ping is working both ways

the problem is with the ping between:
- LAN B (192.168.2.0/24) and LAN C (192.168.33.0/30) without 192.168.33.1 (address ether on MT) because from 192.168.2.0/24 and 192.168.3.0/24 is OK
- LAN D (192.168.3.0/24) and LAN A (192.168.22.0/29) without 192.168.22.2 (address ether on MT) because from 192.168.2.0/24 and 192.168.3.0/24 is OK
ping results is timeout.

If anyone has an idea where the configuration error is or what could be done to make the ping work between all subnets A, B, C, D, I would be very grateful if you could share it :)


Added after a few minutes: :)
between LAN 192.168.2.0/24 and 192.168.22.0/29 is masquerade that from 22.0/29 to 2.0/24 ping isnt work but schould be work from 3.0/24 to 22.0/29 but isnt.
