I’ve just reinstalled a Dell PE2600 with SBS 2003. I was initially using a single NIC, but was having problems losing DNS resolution. Using info in other threads here I’ve now enabled a second NIC for the LAN side; there are currently no clients connected. My questions relate to whether the config I have now is optimal (or at east correct), and how I should add clients in the future.
Here is the topology:
+ DSL modem connects directly to SonicWall (hardware firewall)
+ SonicWall has fixed IP (WAN side) and LAN IP of 192.168.168.1; routes all traffic to 192.168.168.2 (via NAT); LAN port connects to 5-port switch
+ PE2600 connects to switch via side 1 of dual port NIC config’d as follows:
+- IP 192.168.168.2
+- SN 255.255.255.0
+- GW 192.168.168.1
+- primary and secondary DNS are set (via CEICW) to the ISP’s DNS’s, but IPCONFIG shows them as 192.168.168.2 (the server), so I assume these are routed internaly by SBS 2003.
+ The second side of the dual-port NIC is disabled.
+ The LAN-side gigabit NIC is enabled and configured as follows:
+- IP: 192.168.168.3 (but, see below)
+- SM: 255.255.255.0
+- GW: (blank)
+- primary DNS: 192.168.168.1
+- secondary DNS: (blank)
Viewing the DHCP config, I can see that I “192.168.168.0 (SBS Scope)” was configured automatically.
Now for the questions:
1) is the above optimal, or at least correct?
2) should I remove the primary DNS setting from the LAN-side NIC? Another thread here suggests that I should.
3) should I use a different address and subnet for the LAN-side NIC, such as 192.168.1.1? If so, will the DHCP scope be reset automatically, or will I have to do that manually?
4) since I have a hardware firewall, is there any way I can completely disable the SBS 2003 firewall?
