Sorry but I'm a little confused here. Normally your "network" is the other devices at your same location and they can't connect via router. They need a switch if wired or something similar if wireless.

A router would be needed to connect you to devices outside your network.

Are you trying remote access to other PCs on your network?

What sort of remote access? IRC DCC only or have you tried other methods?

What, exactly did the mIRC tech support folks have you try? I know it didn't work and knowing what didn't will keep us from wasting time on trying the same things.

 

Doesn't that depend on the individual Router ?

Or am I missing something ?

I had three machines and a Printer plugged into my Router. But the Router I have is a Linksys BEFSR41 with a builtin 4 port switch.

BB - you have stuff plugged into a switch. All packets addressed to other PCs on your home network never see the router. The switch passes them along as needed.

If you address a packet and it is not for an IP on your local network, the packet is passed to the router to 'route' (tech speak for 'send somewhere else'. Some larger devices will have multiple route tables set up and will direct stuff differently depending on the IP address but the ones we use at home are simple. A packet is either for 'here' or it is sent out and will be processed by a big router operated by the ISP.

Not to go into too much detail but when we talk 'network' we are talking a group of IP addresses that, based on the subnet mask in use, are part of a single segment.

Usual for home networks is to use a netmask of 255.255.255.0 and when you use that one, all IP addresses that match in the first 3 sets of numbers belong to the same network so
192.168.0.1 and 192.168.0.55 are and
192.168.0.1 and 192.168.1.1 are not.

If 192.168.0.2 and 192.168.1.2 are attached to the same switch, they can never see each other.

If they are attached to different switches and those are connected to routers, the routers can connect them as long as they have a route table entry to tell them where everything lives. So if 192.168.0.2 sends a packet to 192.168.1.2, it will go to that network. If 192.168.0.2 sends a packet to 47.126.35.41, the router will not know the exact destination location and will pass the packet along to a 'more senior' router.

My case at work is typical of larger networks. Within our building we have 3 network segments. One is 'business' and is the personal computers for the most part. One is 'process' and is the various production servers and some PCs. The other one is for server backups. Business machines have their gateway address pointing to the business router. It knows where the process router is and passes those packets along. Company wide we have dozens of networks and the routers have 'route tables' to locate them as well. Unknown addresses are internet or mistakes and are sent to a border router for pass-along to our ISP.

The key for us is that business and process have totally different sets of wires with no direct connection. Otherwise it simply would not work.

 

OK. We may well be mis-understanding each other here.

What I meant by depending on the Router was, the capabillities of the Router.

My so called Router includes a 4 port switch and a DHCP server. So I originally had everything plugged directly into the Router. But I now have a separate 4 port Switch. ( should have been 8 but I messed up )

I can ( and just did ) disconnect the Router from the Internet the LAN still worked fine. So I put that back together.

I disconnected the 4 port switch from the Router and the only things ( two machines and the Printer ) that connected were the ones that were already on before I disconnected.

The 3rd machine did not connect until I reconnect the switch to the Router and restarted it.

Now is this telling me that My Router is doing one hell of a lot of work.

And if I had just the switch alone I would need to MANUALLY assign addresses to each machine ? Nope. I will gladly let the Router do the work.
