Port Forwarding


Recommended Posts

Hi

I am following this guide to get ports forwarded on my Beetel 450TC1. But is points out for a static ip to be configured. Not sure do i actually need it, also does that mean getting one from sites like dydns? Would that increase the speed (although technically it does depend on the seeds and the sharing)

Cheers

When you forward a port, it asks the IP address of the machine you want to forward ports for, if you do not set a static IP and reboot the machine and its IP changes, then your port is not forwarded for that machine anymore

Set a static IP in the network adapter IPv4 settings on the machine you are needing to forward them for

dyndns is not needed, that is a workaround for people with dynamic external IPs who need a static route to the network from elsewhere, ie. running your own webserver

As detection pointed out yes you can set a static on the box your forwarding too. Or just setup a reservation in dhcp so that box always gets that same IP. Does not really matter, all they mean when they say your box should be static is that its IP address is not going to change.

The problem is you forward to box A at say IP address 192.168.1.42, now for whatever reason maybe you leave that box off for a few days or something and it lease expires. And some other computer your box B is turned on and gets 192.168.1.42 -- your forward will not longer be correct, this could just mean your service would no longer work. Or it could be a security issue that a port you wanted to send only to A is not to B, maybe computer B is not secured in the way A was, etc.

I too am curious how you get to "Would that increase the speed" - you mention seed, so I assume your talking p2p. Swarms do not use an fqdn to access peers, just IPs involved. So you having some having some fqdn that points to your public IP is going to have nothing to do with anything related to p2p.

Where they come in handy is for people accessing your forward when its something like web or ftp/ssh server etc. Then you can give them the fqdn vs an IP.

"r people with dynamic external IPs who need a static route" - I have a dynamic ip from my ISP, that changes on router reboot after some times.

"setup a reservation in dhcp so that box always gets that same IP" - I have a laptop (uses wifi obvsly to get to network) and my bro has a desktop wired to the LAN of the router, now if i set up range in DHCP, how would that assign a specific IP from the range to my machine only and not to the desktop's adapter? Do i need to bind my MAC address may be to the IP i put up in DHCP, sort of mac spoofing that we do in bridging and repeating of access points.. so that the static IP is bound to that specific adapter every time?

Yea but unless you are running one of the above that Budman has listed you don't need a static route to your external IP, torrents just need your Internal IP, (The 192.168.x.x one) of the machine you are running the torrent client on to remain static either by setting static on that machine, or as Budman suggested, setting a DHCP reservation so the router assigns the same IP to that machine each time

^ why not? I doubt the janitor has to take a IT related test to work there ;) Not all positions at an IT company are IT related.

Now back to the topic - lets stop using the term route or static route in reference to a domain name that points to his public IP. This has nothing to do with routing at all.

You sure and the hell do not need a fqdn to point to your public IP for p2p. But sure if you won't one get one -- I have quite a few of them, xxx.homeip.net, xxx.user32.com, xxx.no-ip.info. This way you can use different fqdn for different things or different services. They are free so what does it matter if one or 100 of them ;)

As to the dhcp reservation -- your getting it

"i need to bind my MAC address may be to the IP i put up in DHCP,"

But its not spoofing ;) yes you tell the dhcp server that for mac address aa-bb-cc-dd-ee-ff always gets say .105 our of your pool of .100 - .150. And if don't see a aa-bb-cc-dd-ee-ff mac, then you "reserve" that IP and do not give it out until you do.

What nice about this vs setting as static on the machine, is that for example with your laptop I would have to assume it might get on some other network. Well if you had set a static IP on it, then it more than likely would not work when say it goes to school or starbucks wifi connection, etc. But with only a dhcp reservation. Box still set for dhcp, so he gets whatever IP and info he needs for any network he connects too. But when on your network he would always get that ip that ends with .105

Another nice thing about using dhcp reservations vs static, is if you need to change something - maybe you get a new router with different IP settings, or maybe you want to hand out a different dns or some other info via dhcp like netbios node type. You don't have to go to the machine and do anything, he well just get this new info upon reboot or renewal of his dhcp lease, etc.

Yea bad choice of words, I was using "route" as in 'path' ie. The quickest route to the shops is...

LOL You cannot possibly work for Google without knowing how Port Forwarding works ...

got it.......

BTW : i takes more dan a janitor skills to get your a** into sergey n brin's office and run speedtest.net on their machines. :cool:
