VPN PIX 506e to Linksys RV042?

CTS-Tech1
Level 1
Level 1

I'm kind of a Cisco rookie and need help setting up a VPN:

I replaced a Netopia R910 with a Linksys RV042.  I duplicated the settings the best I could.  I'm trying to re-connect the site-to-site VPN from our network (192.168.0.x private, xxx.xxx.109.202 public) to the remote network (192.168.38.x private, xxx.xxx.131.50 public).

In the Linksys, the VPN shows as connected but no traffic is coming across.  I can't ping anything on the remote subnet.

It worked fine with the R910 and no settings have been changed on the PIX, other than new pre-shared keys that match.

Here is the PIX config and the RV042 config is attached as an image.

Thank you for your help!

For NAT exemption, you would need to add the following:

access-list inside_outbound_nat0_acl permit ip 192.168.38.0 255.255.255.0 TomJ 255.255.255.0

Are you using static crypto map or dynamic crypto map on the PIX for the VPN connection to the Linksys?

The configuration does not seem to match as there is not static crypto map for x.x.109.202 as well as the subnet 192.168.0.0/24, and the NAT exemption also hasn't included the 192.168.0.0/24 subnet as well.

What was the old peer ip address? as well as the old private subnet on the Netopia router?

For NAT exemption, you would need to add the following:

access-list inside_outbound_nat0_acl permit ip 192.168.38.0 255.255.255.0 TomJ 255.255.255.0

Not sure how it works before, as it couldn't possibly be working as you don't have any reference to 192.168.0.0/24 on your PIX configuration applied to the VPN configuration nor the NAT exemption statement. Can you please add the access-list advised earlier, and try to ping between sites, and share the output of :

show cry isa sa

show cry ipsec sa

from the PIX.

Thanks!!!

I can ping and RDP to the .38 subnet now.

It was working with the R910... weird.

Im not sure about the static or dynamic crypto map.  How can I tell?

The old public and private IPs on the Netopia are the same.

Also, the 192.168.38.x subnet does not need access to the 192.168.0.x subnet.

But 192.168.0.x needs access to 192.168.38.x.

Perfect, looks like it uses dynamic map then. I assume all is back to normal now.

Please kindly mark the post as answered if you have no further question. Thank you.
