Hello!

Right now I'm sitting here on my workstation connected to my ADSL-modem 
trying to figure out how to make my gateway route things for me. I haven't yet 
found detailed enough documentation on how to set up this type of network. The 
handbook doesn't seem to help me much.

I assume changes are made in rc.conf and rc.conf alone with 
gateway_enable="YES" and by running ifconfig on all NICs and desires IPs.

I picture the network layout to be pretty basic;

WORKSTATION (rl0) === GATEWAY (lnc0/ep0) === ADSL-MODEM
10.0.0.3 ============== 10.0.0.2 ============== 10.0.0.1

However when it comes to setting it up,

--Workstation's rc.conf:
ifconfig_rl0="10.0.0.3  netmask 255.255.255.0"

--Gateway's rc.conf:
defaultrouter="10.0.0.1" (ADSL-modem, Cisco 677i-DIR)
ifconfig_lnc0="10.0.0.2  netmask 255.255.255.0"
ifconfig_ep0="10.0.0.3  netmask 255.255.255.0"

You can probably understand that I don't really comprehend networks. I'm also 
wondering how to use a different set of IPs. But how can my ADSL-modem 
modem be recognized when I suddenly change its IP in defaultrouter? And, I've 
also heard that I should not have multiple NICs on the same subnet.

This is all so confusing :/

Regards,
Johann
