Once you have finished setting up your LinkSys router, and you are connected to the Internet, you still have a little work to do. This is in the manual, so follow the directions in it!
Open up a browser and type in 192.168.1.1
A menu will open. Type nothing
in the top box, in the 2nd box type: admin
~~~~~~~~~

For mIRC
to work properly with your router setup, you need to 'forward' (or open/allow)
certain information to come through the router to your pc for mIRC
to use. Click the Advanced tab (orange tab shown above), then
click the 'Forwarding' tab.

Now, here is where it might get confusing but once you understand it, it's really very simple, . You need to 'open' the router door to allow for ident and DCC ability. You need to do this (open this door) for each of the computers connected to your router.
The green circle is where your computers 'address' (ip for router) is located. The last placement value diferenciates between different machines connected. Machine A = 100. Machine B = 101
The red
circle indicates what 'door' (ports) to open,
or what range of ports. Circled in red
is 113, this number = ident.
So to enable
ident to work, 113 is filled in both boxes.
The pink
arrow shows both machines, connected to this
router, with ports 8000 - 9000 open.
The orange
arrow shows only Machine A with ports 4990
- 5000 open. Both sets of ports could be for DCC sends/chats
~~~~~~~~~
Once you are
finished with your port forwarding, you need to make mIRC
match which ports you have opened for DCC.
File - Options
- DCC - Options Here you will see the location for the
DCC Ports setting. You need to match the ports you want to DCC on,
with those in the router forwarding section.
~~~~~~~~~~
Local Info Settings:
Be sure you
have your 'Lookup method' set to [x]Server


( File - options
- connect - firewall ) be sure to UNcheck the firewall settings.
*Note: This was MY experience
with this specific type of router (LinkSys EtherFast 4 port BEFSR41
v.2 ).
Read the instructions that came
with your router. This cannot be stressed enough.
