unable to establish a vtpn tunnel cisco router 871-> symantec gateway 5420

Hi,

I have a problem to establish a VPN tunnel between a cisco router 871 and a symantec gateway 5420.

The cisco router is in NL and the symantec in DE.

Now whe have already to setup the internet line in NL. that works fine.

But when i configure the VPN tunnel to Germany i get some problems.

With the ezvpn config. I get an active connection but it fails on phase ID 1

with the DMVPN i don't get any connection it says down-negotation

with the "old" way vpn I had an active line but after 1 day not anymore and it doesn't get active any more.

Unfortenally I don't get much information of the German IT company. Who had configured the symantec gateway 5420 in NL and Germany. but the 5420 in NL died last week so with a fast sollution we picked a cisco 871 router.

I replaced the ezvpn to a normal vpn tunnel but now i get UP-NO-IKE.

what could be possible wrong??

I think you need to again enter the authenticatioon keys manually on the router. Also you should clear all session information before attempting to create a new VPN session.
