My Cisco vpn client drops out regularlly ( ever 10-15 min ) and I get this error message.

When VPN went down:
Secure VPN connection terminated locally by the client.
 
Reason 412:    The remote peer is no longer responding.

How do I resolve this???

I have the client going through a switch then PIX 515e then through a ADSL link.    If I connect to the vpn and do not send any traffic through it stays up but does an idle timeout after 30min, which is fine. But when I send through any large amount of traffic it disconnects and gives the above error message. I do not have any firewall on the PC. I "THINK" I have the PIX setup correctly to allow IPSEC traffic. So is it the PIX or the ADSL link or the switch.

The switch is set to 100full as is the PIX. I am allowing ip and tcp to go through the PIX.  Any ideas on how to fix. The ADSL link is OK as it does not drop out at all. Any ideas please???It is driving me up the wall.

Do you have
  isakmp nat-traversal 20

Do you have
 isakmp keepalive 10

Did you set your VPN Client to use MTU of 1300? There is a SetMTU utility that installs with the client.
What version client?
What version PIX OS?

Doesn't matter if you are using NAT on the PIX, if the PIX is the VPN client endpoint then it can handle the client being behind a NAT firewall.

Upgrade the client to 5.0.0340
Which exact version of PIX 7.?

It was the upgrade of the VPN software that stabilized the VPN . Thanks.
