Hi, The netmask for the rest of the network should remain the same so that each machine still thinks it's talking on a /24 (the ppp server is responding to ARPs so nobody can tell that the ppp server isn't actually just a multi-homed host).
Only when a packet gets to the ppp server is it actually routed (which happens because the IP number doesn't match after all -- despite the ARP table). I guess the missing bit is that the timeclock machine needs a special routing table with 192.168.1.234/30 on it's crossed-over ethernet interface and 192.168.1.233 as the default route, allowing data to get back to the rest of the /24 subnet. When you get it all working it'll start to make sense (if it doesn't already). On Tue, 22 Mar 2005 14:06:21 -0600, "Chris Tusa at Linisys, LLC" <[EMAIL PROTECTED]> wrote: > Brian, > > Very helpful.
