Round 2 RE: [FW1] oh so frustrating IKE VPN problem




I'm not sure I follow you.  I've established two group objects, each
containing a private network and their respective FWs.  There doesn't seem
to be any way to NAT the encryption domain.  I do, however, have each
network (minus the FWs) doing hide behind NAT of the public interface
address of the respective FWs.  Is that what you meant?  If I remove the NAT
there, my internal networks can't reach any public addresses which is a
requirement for us.

The CP doc said to create two group object with my internal networks and FWs
in it for each side of the tunnel and use the group as my encryption domain.
Should the encryption domain just be the internal network instead of the
group (ie: minus the FW)?

Thanks.

Chris

Add an address translation rule that says that both encryption domains will
communicate between each other without address translation (original).
This rule must be on before all other NAT rules.
Give us some more information about the messages that you get in the log,
when you try to communicate between two sites.
HTH,
Michael.

Hello, all.  I've been bumbling through a multiple FW-1/VPN-1 (4.1 SP2 on
one and 4.1 SP1 on the other) installation with the help of you all for a
few weeks now.  I'm at the final step and can't quite get it though.  I
followed CP's page on setting up an IKE site to site VPN tunnel between two
CP FWs ("How to setup gateway to gateway Single Entry Point (SEP) IKE VPN
tunnel with VPN-1 4.1? ").  

10.3.0.0/16 --> FW <--> Internet <--> FW <-- 10.1.0.0/16

Both private networks can reach the internet successfully with hide behind
NAT.  The trouble comes when I try to reach a private network from the
other.  I keep seeing drops due to the rule:

(both private nets) (both private nets) ANY ENCRYPT LONG GATEWAYS

I'm trying to do shared secret IKE with any encryption and hash.  The
encryption domains are two groups with their respective private networks and
FWs.  For the interface security of the FWs I have "others" associated with
the external interfaces and "this net" for all of the internal interfaces.

Any thoughts on how to get this going?  Will CP do the routing here or do I
need to add routes on the OS beneath it?  Licensing is correct also.  The FW
module works perfectly.  Sigh.

Chris
