What exactly is the difference between Port Forwarding and Virtual Severs (in my router I only have virtual servers)?

Port forwarding is a 1:1, fixed port mapping from a external port to a private IP.

Internet <-> 200.1.2.123:12345 (WAN IP) <-> 192.168.1.8:12345 (LAN IP)

Virtual servers allow mapping a external port to a host behind the router which is listening on a different port. This allows you to have multiple internal hosts listening on the same port and still be reachable from the Internet via different external ports.

         <-> 200.1.2.123:12345 (WAN IP) <-> 192.168.1.8:80 (LAN IP)
Internet <-> 200.1.2.123:12346 (WAN IP) <-> 192.168.1.9:80 (LAN IP)
         <-> 200.1.2.123:12347 (WAN IP) <-> 192.168.1.10:80 (LAN IP)

If you create a virtual server where the external and internal ports are the same, there is essentially no difference with port forwarding.

Similar question: what about difference between QoS and Bandwidth Management? Are they the same? Can trafic shaping be done in either of these?
From what I can tell, bandwidth management allows to restrict ingress and egress speeds.

QoS means "quality of service" and is a concept in telecommunications, where an attempt to maintain an base, reasonable level of quality and reliability for customer traffic. QoS may use bandwidth management techniques to achieve these goals. They're near-synonyms in that regard.

I'm trying to do traffic shaping in my router but I guess I can't.

Care to show a screenshot of these settings in your router?

Cheaper ones may only allow basic rate limiting and "guaranteeing" of traffic on certain ports and that's it.

If you haven't done so already, I would check if your router is compatible with DD-WRT, which seems to be the bomb.

As fair as I can tell this is the only bandwidth config available. Would the PDF suffice? The router is TP-LINK WRN740N

[anon]

That's just a global WAN rate limiter, it won't do anything similar to what you were looking for. Try something like http://www.cfos.de/en/cfosspeed/cfosspeed.htm

I did a search; unless you made a typo on your router model and it's actually WR740N, it's sadly not supposed by DD-WRT.

[Master Razor]

Yeah but cfosSpeed is a software solution. Would of been great if it worked through hardware.

I've been reading about broadcast storms (i was like ). Imagine a huge network with such a problem...

Get a better router?

OpenWrt can be tricky to install. They have an extensive wiki and support for many routers.

No luck searching for "TP-LINK WRN740N". There is, as anon points out, TL-WR740N, which too is supported by OpenWrt.

I've always wanted to pick up the phone when someone calls and say "hi, I'd like to order a large fugazzeta pizza with four faina and two cokes, for <street name>".

[Master Razor]

True, it was a typo. I meant TL-WR740N.
All TP-Link are decent products for those with strict budgets.

I would add DD-WRT but I'm currently afraid that it'll void my warranty. You can never be too careful.

After much intense calculation, it has been decided that your thread is already in the forum that you wish to move it to.

Deep Thought should be jealous.

I like these messages in vB.

If you did it on your router using DD-WRT it would still be software based.

If you install a custom router firmware, yes it most likely will void the warranty.
With that said, if you read the manual thoroughly, search extensively on the subject et al, before installing the firmware, there is very little chance you'll get a bricked router.

I've read quite a few times that you can most likely unbrick it as well using telnet (or something similar? can't recall).
If you really want to try, but are scared to, look up the unbricking procedure first. If you feel comfy with it, there's less to worry about :)

[Master Razor]

I'm not talking about bricking it. Let's say there is a mechanical failure with it and you can't restore its original firmware. What do you do then? They won't accept it if an unofficial firmware was installed.

Talking about routers and failures, next Wednesday I have an interview for a goverment network management job

those usually happen 2 days after warranty has expired anyway
