The SonciWall has been put behind another device and despite everything being forwarded to the SonicWall I can no longer VPN in (UPDATE: "The peer is not responding to phase 1 ISAKMP requests" is logged in the global VPN client).
I think this is something to do with the IKE exchange using ISKAMP (although the 2 UDP ports Group policy sets in the firewall are also forwarded) being dropped by the new device.
Is there anything I can do? Is it possible to use a different method than IKE to establish VPN?
- It is a SonicWall TZ170
- Internet connection is up
- I have the correct IP - I can connect using other applications
