-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I should point out that there is a "workaround" - to not change the source port number on DNS traffic. The fix is somewhat simple. If you have a line like this in your ipnat.conf: map bge0 0/0 -> 0/32 portmap tcp/udp 10000:20000 Then you need to add another one before it and reload: map bge0 from any to any port = 53 -> 0/32 tcp/udp map bge0 0/0 -> 0/32 portmap tcp/udp 10000:20000 Cheers, Darren -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkiG8JUACgkQP7JIXtvLbFWcPQCgouTL5A74bORZDaQ9lLjLxoDx eysAoJNYdXBhNQ1IjyEJwZlKEsCq897j =HFaP -----END PGP SIGNATURE-----
