I suspect that there will be anomalies with Shorewall, however, because both IP addresses will be broadcast addresses (one the network address and the other the network broadcast address). teastep@Asus:~/shorewall/web$ shorewall ipcalc 68.140.187.76/31 CIDR=68.140.187.76/31 NETMASK=255.255.255.254 NETWORK=68.140.187.76 BROADCAST=68.140.187.77 teastep@Asus:~/shorewall/web$ So, for example, the dropBcast action will drop all traffic to either address. That can be fixed, but it will take a change to the Shorewall code to special-case /31. Also, the 'nosmurfs' interface option cannot be used as it will cause all packets with the gateway address as the source IP to be dropped. -Tom -- Tom Eastep \ Q: What do you get when you cross a mobster Shoreline, \ with an international standard?
