You want the ifconfig_fxp0=... and ifconfig_fxp1=... lines in your /etc/rc.conf file. Currently you probably have something like: ifconfig_fxp0="inet 205.150.82.194 netmask 0xfffffff0 broadcast 205.150.82.207" maybe with some additional options. All you should need to do is change those lines to match the new values. Do this before you power everything down in the old colo, then the machines should come up correctly configured in the new location. > 2) Add the new settings. > Here are the details from the new provider: > Network: 65.39.193.144 > Gateway: 65.39.193.145 > Subnet Mask: 255.255.255.240 > Useable IP Range: 65.39.193.152 - 154 > > fxp0 will be plugged into a switch which in turn will be plugged into > the providers switch. > I am somewhat confised about the terms.

The gateway address goes in your defaultrouter=... line in /etc/rc.conf. This refers to the host on the 65.39.193.144 network that knows how to route to other networks. Your switch may or may not have its own IP address, but that's not relevant here. You shouldn't need to use the network number anywhere explicitly... ifconfig should be able to work it (and the broadcast address) out from the netmask and host address you give it, i.e: 65.39.193.152 AND 255.255.255.240 = 65.39.193.144 So on your first machine, you probably want: ifconfig_fxp0="inet 65.39.193.152 netmask 0xfffffff0" ifconfig_fxp1="inet 192.168.0.2 netmask 0xfffffc00" defaultrouter="65.39.139.145" and so on for the other two. > 3) CUrrently, I have two boxes that are connected to each other.

My question is, can I pluc the three of them into the same local > switch as the internet connections (fxp0). The switch probably won't care, but you might have ARP problems with that kind of setup. I really not sure though... maybe someone else can clarify what the problems might be?
