Re: [fw-wiz] Cisco VPN client is slow behind new PIX



What are the hosts primarily? Windows? If so, that "inspect netbios"
line will probably be the source of your slowdown.

I recently replaced the gateway at my workplace, we had a Cisco 1721
and upgraded to a Cisco PIX 515E.
After the change my coworkers reported that their connection over
Cisco VPN client was less than half the speed it was before the
change. All the ACL rules that were on the 1721 were brought over to
the PIX.

The connection is from our office through the PIX to one of our
clients. We don't use NAT here, as we have a full Class C IP address.
Here's a sanitized excerpt from the PIX config.
