Hello.
I've got a Cisco PIX 501 that I like to use as my boarder firewall/ router for my home. However, I have found one situation where I have to swap the 501 for a dumb Linksys router/NAT device.
I work from home as a software consultant, and one of the clients I work for has a VPN concentrator that I can not connect to with my PIX inline.
I think I have narrowed it down to the VPN Adapter that is created when I connect to their concentrator.
Ethernet adapter Cisco Systems VPN Adapter:
Connection-specific DNS Suffix . : XXXX.XXX Description . . . . . . . . . . . : Cisco Systems VPN Adapter Physical Address. . . . . . . . . : 00-05-9A-3C-78-00 Dhcp Enabled. . . . . . . . . . . : No IP Address. . . . . . . . . . . . : 192.168.16.2 Subnet Mask . . . . . . . . . . . : 255.255.255.224 Default Gateway . . . . . . . . . : DNS Servers . . . . . . . . . . . : 192.168.1.10
There is no 'Default Gateway'. With the PIX in line I can not connect to their server 192.168.15.2, etc.. With the Linksys in line every thing seems to work fine.
I have tried to contact their network admin to resolve the issue, but they have been very un-responsive. Is there any setting I can change on my PIX?
I'm guessing (as I'm no network guru) that the Linksys router is allowing ARP requests to traverse the device, and the PIX is blocking them since there is now pre-defined route, or maybe this guess is way off, I don't really know.
Any help would greatly be appreciated.
