How to correctly use 2 on board nics
Hello I have a server board with 2 onboard nic's I have set them up in rc.conf as follows defaultrouter=192.168.1.1 network_interfaces=em0 em1 lo0 ifconfig_em0=inet 192.168.1.3 netmask 255.255.255.0 ifconfig_em1=inet 192.168.1.4 netmask 255.255.255.0 The question, is this the correct configuration? If I have both nic's connected to the switch I can ping 192.168.1.1 and 192.168.1.3 and 192.168.1.4 If I have only em0 connected I can ping 192.168.1.1 and 192.168.1.3 If I have only em1 connected I can ping 192.168.1.3. What could the 2 onboard nic's be best used for. I was thinking that in the event on was to fail then the other would still be ok. Any ideas would help.

The most common configuration for using two nic's is one nic is used for your dsl or cable modem connection to your ISP and the second nic services your local LAN. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Ivan Carey Sent: Tuesday, June 05, 2007 6:55 AM To: freebsd-questions@freebsd.org Subject: How to correctly use 2 on board nics Hello I have a server board with 2 onboard nic's I have set them up in rc.conf as follows defaultrouter=192.168.1.1 network_interfaces=em0 em1 lo0 ifconfig_em0=inet 192.168.1.3 netmask 255.255.255.0 ifconfig_em1=inet 192.168.1.4 netmask 255.255.255.0 The question, is this the correct configuration?

Do you want to be able to serve two networks out of the NICs, one from each interface? Do you want to create a gateway of some sort? What is it, exactly, you are trying to accomplish by doing this? ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Quoting Ivan Carey [EMAIL PROTECTED]: I have a server board with 2 onboard nic's I have set them up in rc.conf as follows defaultrouter=192.168.1.1 network_interfaces=em0 em1 lo0 ifconfig_em0=inet 192.168.1.3 netmask 255.255.255.0 ifconfig_em1=inet 192.168.1.4 netmask 255.255.255.0 The question, is this the correct configuration? Manually specifying network_interfaces is deprecated (take that line out). Putting both NIC's on the same subnet and segment but with different IP's like this may not be too useful.. If I have both nic's connected to the switch I can ping 192.168.1.1 and 192.168.1.3 and 192.168.1.4 If I have only em0 connected I can ping 192.168.1.1 and 192.168.1.3 If I have only em1 connected I can ping 192.168.1.3. That is because the route to 192.168.1.1 is associated with em0 at this point. What could the 2 onboard nic's be best used for. I was thinking that in the event on was to fail then the other would still be ok. For that to be most useful you'll want to set something up so they can share the same IP. The lagg(4) (link aggregation) virtual interface has already been mentioned, but I believe it is still only available in -CURRENT. Other possibilities might include attaching ifconfig scripts to link up/down events or [lack of] ping responses on one or both interfaces.
