I'm running a PIX 506 6.3(3). I have the VPN cranked up and working mostly fine. I have defined an ip local pool for my address-pool in the vpngroup. The issue I'm having is that we are using Cisco Softphone and the IP address on the VPN is different almost everytime somebody starts the VPN. That means changing a setting in the Softphone so the audio works correctly. I was looking to increase the "lease" time but I'm not really sure it's actually a DHCP thats being handed out. When I do a show dhcpd nothing comes up. Setting each MAC address to a static IP in the range would be fine also. Just not sure how and if that can be done.
