asked on

remote peer not responding

Hello,

I have configured a pix 515r for vpn connections. When I try to establish a connection the vpn client 3.x calls error – that remote peer is not responding. We are connected is the ISP with a leased line and a cisco 2501. The 2501 is not nat’ing; the outside interface of the pix has been assigned a registered ip.

I enabled the debug for ipsec, isakmp and engine. The pix is receiving the connection but it’s almost as if there is no route back. I have a single route on the 2501 that routes all traffic to the interface connected to the internet, ip route 0.0.0.0 0.0.0.0 serial1. the pix has a route that routes all traffic to the Ethernet interface on the 2501.

Do I need any other routes with regard to the ip pool? However if I connect my notebook directly to the outside interface of the pix with an ip address on the same range, I can establish a connection…

When trying a connection from a remote site, the sites in question are performing NAT, could this be the problem?

Thanks,
Richard

Hi, thanks for the replies,
what i did was as follows:-

- upgaded the pix to 6.3(3) from 6.2 - 633 supports nat-traversal
- used the new client 4.x
- also found article on cisco site relatiing to this problem "Troubleshooting the PIX to pass Data Traffic on an Established IPSec Tunnel" - this was a valuble article.
