possible firewall issue

[dennishixson]

Here is the deal.. I have a CSU|DSU from the local ISP, the CSU\DSU is connected to a linksys hub (the hub has DHCP disabled). From the hub there is a cable doing to the external port on the watchguard x500 firewall. The other port on the firewall is going to the internal network switch. Internet is running fine. Then, I have a Windows 2003 server with 2 NIC’s. NIC #1 has a internal IP address and is connected to the internal network switch. The gateway is the IP address of the firewall (192.168.1.201). All is running fine. Here is the problem, I want some other offices to be able to VPN via RRAS on the Windows 2003 server. So, on the 2nd nic on the windows 2003 server, I plug a cable from NIC #2 to the linksys hub, and assign another public IP address\gateway\subnet\dns provided by the ISP. ( same gateway\sub\dns as on the firewall). When I enable the 2nd nic on the server, internet goes down on the server. If I disable the 2nd nic everything starts running fine again.



I would rather not have to put another box up just for VPN… can you think of what may be causing this?

change the matric for nic's on that server, make the private nic( the fb) preferred to go out. There are chances that the server has same matric for both the nic's thats why that server is not able to go out. Let me know the update please.

I ended up replacing the hardware firewall with a 2003 server running ISA and VPN. Solved my problem.

Thank you
