Hello!
I have this setup:
PC A - RB750 A ← L2TP/IPSEC → RB750 B - PC B
I’ve made the setup according to this link http://wiki.mikrotik.com/wiki/L2TP_%2B_IPSEC_between_2_Mikrotik_routers
The problem is that I am not able to reach PC B from PC A or PC A from PC B. I am able to reach PC B from RB750 A and PC A from RB750 B.
How can I debug the routing problem? Thanks!
If the RBs can reach PCs on the other side of the tunnel it should not be a routing issue.
Are you using NAT? If so, have you configure NAT passthrough from site A to site B and vice versa?
NAT is disabled on both routers. I do not see any kind of packet at the ends, with tcpdump.
Although I do not want NAT, I want to try that too. How do I enable NAT passthrough?
Thanks!
NAT passthrough is simply a rule that tells the router NOT to NAT traffic to the other side of the VPN tunnel. If you are not using NAT, you dont need it.
Hello!
Actually this was not a routing problem, but an IPSec problem, due to the fact that I have 2 different policies for the same networks, but with different endpoints. Once I disable one of the conflicting policies, it works fine. I will open another thread for that problem. Thanks!
