Lief, You can run your connections unnumbered, but this can make it difficult to troubleshoot some problems. Alternatively, you can use public address space (10.*.*.*) for your PtP connections. This will let everything work normally as far as your internal stuff goes. The only side affect would be a strange looking traceroute for people outside your network. If you look around, you'll find that most people do use the /30 for their PtP connections. It's actually considered 100% usage of your IP space, and nobody is going to fault you for doing it or ask you to recover that space before allocation of additional space. -Troy > -----Original Message----- > From: owner-freebsd-isp@FreeBSD.ORG > [mailto:owner-freebsd-isp@FreeBSD.ORG]On Behalf Of Leif Neland > Sent: Saturday, November 13, 1999 5:55 AM > To: freebsd-isp@FreeBSD.ORG > Subject: wasting ip's on dedicated lines > > > We're going to connect several sites througg dedicated lines: > > Our site > | > router 100.100.100.1/24 (cisco 2600, channelized E1 (soon)) > modem > | telco lines > modem > router 100.100.101.1/30 (cisco 1005) > | > Fbsd firewall/proxy outside 100.100.101.2/30 > | inside 192.168.0.1/30 > > > This means I'll use 4 ip's for each remote site on the cable > between router and firewall: > 100.100.101.0: network > 100.100.101.1: cisco > 100.100.101.2: firewall > 100.100.101.3: broadcast > > Next site will use 100.100.101.4 to 100.100.101.7 > > This seems rather wastefull. > > Can this be avoided?
