Hello,
I have 2 UTM's both are connected via S2S ipsec VPN (with their green Networks).
If I try to ping an address of the external interface on one UTM from the green Network of the other UTM, I don't get the answer.
UTM1(green) -> UTM2(wan)
The packet arrives at UTM2(wan). Then a Neighbor Solicitation for the IPv6 address is sent out and that's it. The answer is not sent.
Does anyone has an idea why the UTM behaves that way ?
