Re: New External Nic & untangle server-Problems

Reading back in the thread, I think I see 2 NICs with ISA installed, and the only issue is DHCP leases are not being renewed?

Start an ISA realtime logging query, then attempt an ipconfig /renew from one of the workstations. Watch for blocked DHCP traffic. If you see it, check for custom rules in ISA, and either disable or delete them, or move them to a point in the order where they don't interfere.

a) Check the binding order of these NICs, and what is bound to each. The internal (lan) nic needs to be listed first, and the appropriate services bound to it.

b) don't attempt to run the CEICW if there are more than 2 enabled NICs, disable the NIC that's not either the SBS LAN or SBS WAN nic. CEICW cannot configure a box with 3 NICs.

c) is ISA installed?

No just 2 the UT server feeds directly into the external nic on the SBS
server and the SBS server/internal nic hands out DHCP addresses on the
internal lan. The UT server has its own external address so it easily sits in
front of the SBS server in bridge mode. The inability of the DHCP server to
hand out addresses seems to be spreading as several other client machines
have had to have their IPs fixed at the client in order to see the
inernet........Others still seem to be getting their old addresses at restart
from the DHCP server?????? Checked all the settings you mentioned on the SBS
box and the DHCP server seems to be working and set correctly... Any other
ideas-- anyone else have any ideas??? Thanks

So you are running SBS with 3 nics now?!?

I'll be honest, I've never seen SBS play well with three nics. It just has
too many assumptions on how it should be configured. If you are going to
run untangle, I'd reconfigure SBS as a single NIC machine and let untangle
do its job.
