    Question Cant connect to services within LAN (VNC, APACHE, etc...) (Connects fine thru Router)

    Hello all and thanks for the help in advance, I never post asking for help I usually can come up with a solution on my own but this has me stumped... Anyways my problem is that i seem to be having trouble connecting to any of my services within my LAN. I have port forwarding pointed to my host thru my router and I can connect just fine outside the LAN. I've tried checking my iptables and disabled the firewall (ufw) but still no luck... I'll try to post as much info as I can about my setup.

    Connected to internet thru WLAN0 @ 192.168.10.39 (static IP) 192.168.10.1 (default Gateway) 255.255.255.0 (subnet mask)

    While running wireshark i don't seem to get any incomming connection request's when i try to establish a connection within the LAN. I'm completely stumped as to why my router has no trouble seeing and connecting to the host but everything else on the LAN doesnt seem to want to connect. The router can ping the computer just fine but i have 100% packet loss if i try to ping it from any other computer on the network. I have Linux, Vista, OSX, & Win7 (quad boot, not VM) all installed on the same machine and the other operating systems work just fine as far as being able to connect from within the LAN.

    If anyone can point me in the right direction i'd greatly appreciate it.
