I'm using PDM 3.0 to configure some VPNs on a PIX 501 (and it's more or less the first time I've done this, so go easy!) All is nearly well using the Cisco VPN software, (i just don't get the right gateway IP address) but I'm also trying to set up PPTP so that we can connect using Windows VPNs. Everything connects OK to the remote PIX, but only when using the Windows VPN, I get no gateway address, and more importantly the subnet mask comes up as 255.255.255.255 rather than 255.255.255.0, meaning that I can't browse any resources on the remote network. I'm not so bothered about the gateway, just the subnet mask.<br />
<br />
I can't find anywhere where I can change this - can anyone please steer me in the right direction?<br />
<br />
Thanks<br />

Subnet mask issues

Cisco PIX is a dedicated hardware firewall appliance; the Cisco Adaptive Security Appliance (ASA) is a firewall and anti-malware security appliance that provides unified threat management and protection the PIX does not. Other Cisco devices and systems include routers, switches, storage networking, wireless and the software and hardware for PIX Firewall Manager (PFM), PIX Device Manager (PDM) and Adaptive Security Device Manager (ASDM).

A virtual private network (VPN) is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or travelling users access to a central organizational network securely. VPNs encapsulate data transfers using secure cryptographic methods and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.
