Port Forwarding through Modem AND Router?

[Treijim]

I have seemingly random success with people able to join my servers. Sometimes it's fine and other times I see "Starting arranged connection to xx.xx.xx" etc. in the console but nothing happens and nobody joins. So I have a few questions:

I have a modem and a separate wireless router. The router has ports forwarded (28000-28030); does the modem need its ports forwarded too?

I SEEMED to have more success when I used port 27095 on my other computer and forwarded ports 27090 to 27099. A good idea or just a fluke?

Concerning IP addresses, the modem is 192.168.1.1 and the router is 10.0.0.1 and all computers in the house are 10.0.0.10 and up. Should the router's IP be changed to something like the modem's or wouldn't that help?

Obviously the internet and things work just fine as I'm using it right now.

Any help and ideas are hugely appreciated!

Bump?

this is the same setup I have.
Cable modem connected to a router, and then router connected to my pc/laptop.

setup port forwarding  on your router.  I use 28000-28010 (both tcp and udp).

your local/internal IP numbers should not matter, but sometimes I find that the pc doing the hosting has to be setup with a static IP address.  Mabye this is fixed on new routers, but my old one requires it.

Also make sure you have uPnP turned OFF in your router and in blockland if your using port forwarding.

Shouldn't be the case; the problem you will have with dynamic IPs and port forwarding is that the rule is assigned to an IP... and then due to dynamic IPs being just that... dynamic... they are liable to change.

UPnP is an /easier/ way of hosting, it seems to be more reliable and if you have the option I suggest enabling UPnP (usually under "advanced" in your router settings page (if you do enable UPnP, disable Port Forwarding)

If you want to stick with your port forwarding, make sure you go to Blockland's network settings and Un-Check the box saying "Enable UPnP" or something.... down by where you change what things you download from servers.

You shouldn't need to touch your modem.

Isn't that what he was trying to say?

I read somewhere that that sort of setup (modem and router) gets tricky with ports, since they're on two different networks so they both require port forwarding or at least to be on the same network. That's what I read, anyway, and it got me wondering if it's the reason I have trouble with it.
