Just be careful that any names which are being resolved point to the correct ip addresses. If you don't have a different subnet, you can still do it if you mark the traffic with iptables and route according to the mark. You may need multiple routing tables (again depending on the exact configuration) and a couple of routing rules to ensure that replies are always sent out of the same interfaces on which the queries came in on, Steve. > - -- > Mark Watts BSc RHCE MBCS > Senior Systems Engineer, IPR Secure Managed Hosting > www.QinetiQ.com > QinetiQ - Delivering customer-focused solutions > GPG Key: http://www.linux-corner.info/mwatts.gpg > -----BEGIN PGP SIGNATURE----- > Version: GnuPG v2.0.14 (GNU/Linux) > Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org/ > > iEYEARECAAYFAkxO+4IACgkQBn4EFUVUIO3+5QCgwctCm6Xd4kohggq8RsvPim5+ > iYUAn2jLHQAUejGof9VDCRr3t/HYS9iH > =0XH3 > -----END PGP SIGNATURE----- > > -- > Linux-cluster mailing list > Linux-cluster@xxxxxxxxxx > https://www.redhat.com/mailman/listinfo/linux-cluster -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
