Client to CHR L2TP/IPsec link, not establishing.

Wed Apr 21, 2021 5:24 pm

Has anyone successfully connected via L2TP/IPsec (manual - transport mode) a physical client MT to a CHR Windows Server 2019 dedicated machine (with Vmware Workstation 16 / or other vm platform) ?

I have tried allowing UDP ports 500, 1701, 4500 on windows firewall (on the dedicated server) , didn't make a difference.
Have set a rule on the CHR OS to accept the ports in IP/firewall
All passwords are the same on both sides...

Not able to establish a connection ...

I can ping 8.8.8.8 but like I said am unable to establish a connection ...
The server has a /32 public address and I have requested a separate public IP address from the provider (that is on a different sub-net) . I have connected CHRs in the past when behind a regular ISP modem by choosing VMnet0 Bridged on the VM but since there isn't a DHCP running (as mentioned I have only a /32 public address from the provider) I cannot use that option . So if anyone can please through some help, I 'd appreciate it.

P.S. If you notice on the screen shot it shows as src address on IPsec/policies (this is the server side) 0.0.0.0 when it should show the CHR's LAN address, on the client's side the LAN address appears fine.
