Virtual private networks / Site2Site IPSEC VPN Tunnel (Opensense to Sonicwall)
« on: April 28, 2022, 11:09:58 am »
Dear all,
I am working to setup a IPSEC VPN Tunnel between Opensense (Site A) and Sonicwall TZ270 (Site B).
Unfortunatley the tunnel comes not up.
Error on Sonicwall:
IKEv2 Payload processing error
VPN Policy: LCI VPN; Type: KEY Payload
Error on Opnsense LOG:
parsed IKE_SA_INIT response 0 [ N(INVAL_SYN) ]
received INVALID_SYNTAX notify error
But if I configure IKE V1 (with main mode) instead of IKE V2, the tunnel comes up.
Are the any known issues? What could I do?
thanks in advance.
best regards,
michael
