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