Problem with ipsec VPN Tunnel from only one site

RouterOS General
1

Hallo,
i had to build a VPN connection between two locations. The VPN Tunnel is on and there are no mismatchs in the logfiles readable. I’m able to send data from the Site_243 to the Site_244, no problem, but if i want send data from site_244 to site_243 no chance! I build a testing area with other ip adresses with the same result. All of the testing Routers are hap-lite Routers with the Version 6.32.2. There is a pdf file for understandig the testing area.


The plan:
testumgebung.pdf
Look at the site_243 file export:
site_243.rsc
Look at the site_244 file export:
site_244.rsc
any idea, why i can send data only from one site? Maybe i have tomatos on eyes to see clear about a failure in configuration… ;o))

Greetings and thx for help

Ok, i’m looking intensiv at the export files.

It was a NAT Problem! site_243 has no NAT on ether-1 and site_244 has NAT on ether-1. Killing NAT and the sun is shining… :astonished:))

Result:
NAT is bad!

Ok, forget this thread, have a nice day…
