 Subject:  RE: [m0n0wall] DNS Issues on Opt 1 network
 Date:  Mon, 7 Aug 2006 15:20:03 -0700
I duplicated the LAN rule and created a OPT1 rule which is identical.  Again what is odd is desktops
can resolve when I add an outside DNS address but cannot work when using the server IP.  When I hook
them back up to there Linksys firewall I have no problems.
 
Thanks

Mark-

Make sure you have a rule allowing traffic from the OPT1 interface to the
LAN interface.
