  @fredde: still irritating to getting diconnected from irc,ssh sessions on so forth every once in a while..hope there will be some proper fix out soon use keepalive in your SSH client.  every stateful firewall should disconnect unused SSH sessions after their state table timeout period.  Keepalives keeps the connection up.  as for IRC, I don't know.

  Dynamic DNS Client vs DNS Forwarder

  At system>general enter a DNS-Server sitting at WAN and one sitting at OPT-WAN. Then add a static route for the OPT-WAN-DNS/32 pointing to the OPT-WAN gateway. This way the DNS-forwarder will find the DNS-Server at OPT-WAN.

  enable "nat reflection" at system>advanced in the webgui. This way all portforwarded services will be available by the public IP too. Alternatively you could set up a split DNS szenario that resolves the internal IP of the server for LAN clients.

  Hi Hoba. I had also tried this configuration earlier and this makes resolution work nicely but it does not REGISTER the client with the DC (ie. so that the server can resolve the client on the other end.) The only way this happens is by putting the DC as the first DNS which defeats the purpose. Did I miss something?

  Add DNS entries at services>dns forwarder at the bottom. You also might want to check "Register DHCP leases in DNS forwarder" to make the dynamic Clients resolvable. And btw, the DNS forwarder does caching too.

  No.  It needs upstream routers to resolve from which is obtained either via DHCP or by setting the primary and secondary name servers in system -> general settings.

  Unfortunately all interfaces of a bridge have to be up for the other interfaces to work. This is a known limitation.

  @Sharaz: how can i assign more than 1 search domain via DHCP to clients? I dont think thats possible with the current standard for DHCP. Depending on your client Microsoft have an article here about a possible work-around: http://support.microsoft.com/kb/275553/en-us

  If the repeater clones his mac for all clients connected to it it can break things anyway. However I don't have a wrt54g to test anyway  ;) but there were a lot of discussions at the m0n0 list concerning that device and problems with captive portal with several different firmwares. If you really want to shut that down you have to change your wireless setup to prevent this. The pfSense only can see a macadress and an IP. If something of this or even both is faked how should it tell which one is the original and which one is the fake? Your problem is a wireless authentication/association problem, not a pfSense problem or at least nothing that can be fixed/workaround from the pfSense side in this setup.

  Some things to try (though I'm pretty tired atm so if I talk nonsense please forgive me): enable nat reflection at system>advanced. This way your server should be accessable even by it's WAN IP enable "Register DHCP leases in DNS forwarder" at services>dns forwarder. this way your dhcp clients should be resolvable via their hostname add forwarding DNS-Servers for your clientsdomain if you are running another dns server for these clients at services>dns forwarder

  Sorry, it was right under my eyes. I just looked in the wrong place :-[ What I was looking for more specifically was the next-server and filename options to do some pxe stuff with either anywhereTS.com or thinstation.org, obviously I can do that right out of the box just by modifying config.xml [code] <dhcpd>- <lan><enable>- <range><from>192.168.1.100</from>   <to>192.168.1.199</to></range> <winsserver>xxx.xxx.xxx.xxx</winsserver> <defaultleasetime></defaultleasetime> <maxleasetime></maxleasetime> <gateway>xxx.xxx.xxx.xxx</gateway> <domain></domain> <filename></filename> --></enable></lan> -</dhcpd>
