We had a similar issue with a DSL.
We got also a .255 IP and we were able to bring up connections and also vpn's from and to the same AS, but we were unable to get any packet out of the backbone, also not with linux firewalls.
Finally we have changed the ip to .254

One of our customers got a .255 IPv4 address assigned by sunrise. I know that this can be a valid host address with a netmask of /23 or greater, but the strange thing is, that he can't reach any of our Windows Server 2003 hosts with this IP. Windows Server 2008 Servers in the same subnet are no problem...
Does anybody know of such a problem? Mr. Google couldn't give me any satisfactory results... :-)
There is a old windows bug with .255, maybe it's still not solved.
