Duplicate phase 1 packet detected... Please help!

[tgregory9]

Hi,

Using our PIX 535 with version 7... i've got everything set as good as I can see... when trying to establish a VPN direct to the PIX I get the following isakmp debug messages:

Group = ul-csnetworks, IP = 20.0.0.2, Duplicate Phase 1

packet detected. Retransmitting last packet.

Aug 30 15:32:58 [IKEv1]: Group = ul-csnetworks, IP = 20.0.0.2, Duplicate Phase 1

packet detected. Retransmitting last packet.

Aug 30 15:33:03 [IKEv1]: Group = ul-csnetworks, IP = 20.0.0.2, Duplicate Phase 1

packet detected. Retransmitting last packet.

Whatever I do I cannot seem to fix this.. any ideas? :)

ps, im a n00b when it comes to VPNs!

Thanks

Tim

Does the tunnel ever come up? Those errors are not always fatal - I have seen them before, but not quite sure what causes them. What does your config look like? What is on the other end connecting - the software vpn client?
