Help with site-to-site VPN

exxor · Aug 24, 2006

Hi!

I have problem with a VPN tunnel between a pix 515E (6.3) and a Shiva Netstructure. He says (the Shiva admin that is) that this configuration is working agains other Ciscos. So i belive there is something wrong in my end.

It i interpret the debug correctly it fails in phase1.

What can I try next?.. Im pretty stumped about what to do next. Any help is greatly appreciated!

Debug:
ISAKMP (0:0): sending NAT-T vendor ID - rev 2 & 3

This is the settings I got from him:

Those look ok. Is PFS set?

boymarty24 · Aug 24, 2006

Only thing thats strange is

access-list nonat permit ip 192.168.100.0 255.255.255.0 213.115.25.x 255.255.255.224

Cant really see any use of this. I would remove it and try again

exxor · Aug 24, 2006

Supergrrover: No PFS is not set.

boymarty24: That line is so no NATing should not accure between inside and DMZ. Nothing to to with this.

boymarty24 · Aug 25, 2006

Ooops,

Sorry i didnt notice that your dmz and outside ip almost was the same. Thought that it was your outside ip in that statement

exxor · Aug 29, 2006

Now we have gotten a bit further with this matter.. He added my 192.168.100.0 net in his config, and now the Tunnel is started in my end. He cant se it in the shiva.

Im getting a tunnel that bounces up and down every secound.. And a lot more debug info. I just cant see whats wrong in the debug, it says XZXZX_NO_ERROR everyware..

Can you help me locate the error?

What is the remote network that you are trying to reach through the VPN?
Things to try - Add this line to your config
crypto map map1 20 set pfs group2
just to humor me and see if the tunnel stays up.

Also kill the conduits and make them into an ACL.

Im afraid that did nothing for the tunnel..

How do I convert my conds to ACLs? Actually newer worked with ACLs before..

Supergrrover · Sep 5, 2006

conduit permit icmp any any
conduit permit tcp host sun eq

http://www any

conduit permit tcp host sun eq https any
conduit permit tcp host mail eq smtp any
conduit permit tcp host mail eq pop3 any

Would go -

fixup icmp error
access-list outside_in permit icmp any any
access-list outside_in permit tcp any host sun eq www
access-list outside_in permit tcp any host sun eq https
access-list outside_in permit tcp any host mail eq smtp
access-list outside_in permit tcp any host mail eq pop3
access-group outside_in in interface outside
