Hi All,
I have been at this issue for weeks and for the life of me I cannot find the issue coressponding to the Logs.
Situation:
I got 4 Offices to connect to each other: A / B / C / D (apart from B to D this is not needed)
A <> B works
A <> C works
A <> D works
C <> D works
B <> C seems to work for a brief moments and then it breaks.
with these Logs.
not establishing CHILD_SA due to existing duplicate {6198} with SPIs c7ff3fe7_i c31373cd_o and TS
for some very funky reason, it created two Phases...
All tunnels are setup as per OPNSense Guide and each of them works except the B to C
OPNSense Guide (https://docs.opnsense.org/manual/how-tos/ipsec-s2s-conn.html)
After long time of troublehsooting the same IPs that seem not to be able to see each other.. I figured there must be a dead space.
and after retyping the IPs caarefully it worked like a charm.
Sorry for the Topic!
