My network is on the 192.168.10.x subnet and I've made triple sure than LAN2 is set on a different subnet. Based on the thread above, I looked at my eth0/1 config files via SSH. These are posted below. I am by no means a Linux guy, but I'm trying...
#!/bin/sh /sbin/ifconfig eth0 up /sbin/ifconfig eth0 mtu 1500 /sbin/udhcpc -T 5 -n -h `hostname` -i eth0 > /dev/null 2>&1
#!/bin/sh /sbin/ifconfig eth1 192.168.2.101 netmask 255.255.255.0 broadcast + /sbin/ifconfig eth1 up /sbin/ifconfig eth1 mtu 1500
What else can I do to get a static IP address to work?
Unfortunately I did not receive any assistance from the board on this topic, but I eventually solved it myself and wanted to share in case others run into this problem. My setup is slightly different from many N2100 owners because I have a WLAN module installed. I had played with this module at one time and at that time had set the WLAN IP address statically to something in the same subnet as that assigned to the N2100 on LAN1 via DHCP. After playing with the WLAN, I set it to disabled (all fields were greyed out) and never thought twice about it. When I tried to change the IP address on LAN1 from DHCP to static I received the "other Network Interface Device in the same segment" error. The conflict was in fact not with the LAN2 settings, but with the old settings on the disabled WLAN. I re-enabled the WLAN, set it to some dummy subnet, re-disabled the WLAN and then was able to change LAN1 to a static IP address. All good now.
