Hi,

I have two pc's (WinXP SP1 on both) networked through a 4 port ADSL
Router/Modem. I have no problems with the local network, which appears to
work fine and can access the internet from both pc's too. The problem I have
is trying to connect to either pc from an external source; ie a friends
computer. I seem to be able to ping the WAN IP address shown below with no
problem, but cannot ping either pc on the network ....I know the LAN IP's are
no good for this, but don't know what IP address i should enter to ping the
pc's sucessfully. I've heard someone mention NAT but am not sure how to go
about setting it up? is there an easy solution!!

Any help would be appreciated and also prevent me from becoming prematurely
bald!!

WAN
IP Address: 212.84.102.55 Subnet Mask: 255.255.255.0

Computer 1 LAN IP Address: 10.0.0.2 Subnet Mask: 255.0.0.0
Computer 2 LAN IP Address: 10.0.0.5 Subnet Mask: 255.0.0.0

DHCP Server: 10.0.0.2
Default Gateway: 10.0.0.2
DNS Server: 10.0.0.2

Thanks

Neil
