This looks like the same problem I'm having. Most NAT is happening, but every so often an internal IP is 'leaking' through. The leaked ones don't appear to be any different to similar non-leaked ones. The only pattern I have noticed so far is that they all seem to originate from Opera 10.01, but I don't know if that could actually make a difference.
I do know that I started seeing this problem at about 3pm on October 29th, because I was half way through updating my laptop to the new release. I haven't updated either the server (which has the USB727 in it) or my desktop yet though. The leaked packet come from both my laptop and my desktop. I've included some system info below, but let me know if you need more [code] SERVER: Description: Ubuntu 9.04 Release: 9.04 ppp: Installed: 2.4.5~git20081126t100229-0ubuntu2 Candidate: 2.4.5~git20081126t100229-0ubuntu2 Version table: *** 2.4.5~git20081126t100229-0ubuntu2 0 500 http://us.archive.ubuntu.com jaunty/main Packages 100 /var/lib/dpkg/status bind9: Installed: 1:9.5.1.dfsg.P2-1ubuntu0.1 Candidate: 1:9.5.1.dfsg.P2-1ubuntu0.1 Version table: *** 1:9.5.1.dfsg.P2-1ubuntu0.1 0 500 http://us.archive.ubuntu.com jaunty-updates/main Packages 500 http://security.ubuntu.com jaunty-security/main Packages 100 /var/lib/dpkg/status 1:9.5.1.dfsg.P2-1 0 500 http://us.archive.ubuntu.com jaunty/main Packages DESKTOP: opera: Installed: 10.01.4682.gcc4.qt3 Candidate: 10.01.4682.gcc4.qt3 Version table: *** 10.01.4682.gcc4.qt3 0 500 http://deb.opera.com stable/non-free Packages 100 /var/lib/dpkg/status [/code] -- nat routes internal ip's over extrenal networks lan ips over wan networks https://bugs.launchpad.net/bugs/269081 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
