Connecting with a node behind a router/hub

[Phonedog911]

first we used my dad's computer as my gateway because it had routing capabilites(it was connected to a hub that split off to my comp and my brothers comp. then the router(i got it for xmas) and the problem with both setups is that people cant connect directly to my computer via ip(they could connect to my dad's tho). i thought there was a way to connect to a lan from the intenet and then connect to a node on that lan but i guess i was wrong. the router is setup as my gateway... im using it to post these messages

just curious... is there ANY way somebody could reach my computer remotely while im behind this router??(would i have to forward all ports to my internal ip or something?)

oh, and what do you guys mean by demilitarized zone? is that just unplugging from the router and pluging straight into my modem?

Unless you initiate the connection so the router can keep your connection 'state' and knows where to forward those packets, you will need to port forward or set your PC on the DMZ. If you decide to port forward you need to disable the routers abilty to act as a DHCP server and give your NICs static IP addresses, that way you can assure the machine hosting the game has the matching IP address that you put in to forward to.

If your router supports it, you can set the last port of your router to act as a DMZ port instead of a LAN port. This puts the machine connected to it out there without the routers firewall protection.

ok, so i get it all configured to have the last port(you mean the physical port on my router, right?) as the dmz, then how does my friend connect to me? does he use my 192.x.x.x address or the other one?

In order for him to connect to your private IP, you'll have to set up a VPN tunnel between him and you.

If you and your friend are both running Windows XP, you can learn how to set up the VPN tunnel by reading this article from the Microsoft Knowledge Base

Also, could you ellaborate a bit on your friend's network setup, as I'm a little confused. Does he connect through a proxy? (Is his modem connected to another computer on his network through which routes?)

[Phonedog911]

im not totally sure about his network, id have to ask him, but i think he has a laptop that acts as a gateway, then its split to his comp, his brothers, his mom's, etc. by a hub. or something...
thx for the help

If he's connecting through a gateway, you should be able to set up the VPN no problem if he's using the ICS in windows or something like WinProxy (I'm assuming the laptop runs Windows).

Best of Luck

Phonedog - There is a lot of confusing advice here.

Have you managed to play you game online yet?

All you need to do is forward the port the game uses on your router to the internal IP address of the PC that the game server is running on - The advice Maestro (sp?) gave you is the one to concentrate on.

If you are still stuck, send me a PM and I'll try and help. Let me know the make & model of the router.

Didn't I already say that?

I think maestro has the best solution. Depending on what type of NAT and /or proxy capabilities your router supports, you could simply set up a DMZ pass-through on certain TCP/UDP ports. You just set up a maping in the router to route packets that come in on router IP port x to computer IP port X.

Steve is right though. That's all there really is to it.

I tend to ramble and over simplify things (or over complicate, depending on your viewpoint )

if i understood u very well, i guess u just have to do a little subnetting to save ur self all the stress. if u want only two nodes on your network, u will have to sub net ur router ip
233.346.45.31 using a submask 254, then u got ur self too network ips u can assign to ur comp and that of ur dad. :d
