Need to select a given range for my port...

It depends on the services you are forwarding to your internal servers. If you are forwarding for a web server then you will want to forward ports 80 and 8080 and possibly 443 for https.

It is recommended that you only forward the ports that are needed so you should not need to forward a range of ports.

hiya
if you put a server behind a router , then you need to open ports
as that1guy15 said 80 and 8080 for web server
there are some other important port as
53 = udp
here is list of port
http://www.governmentsecurity.org/articles/CommonPorts.php

ssh, dns,smtp

Extra note :

by port fowarding : request will come via your public ip to your router, now you will have to forward that port to your server.

suppose your server has ip of 192.168.1.2

from router, you will have to select port support 25 [ smtp request] to 192.168.1.2

so your router will forward the request to that server.

now suppose you have web server in another pc, which ip address is 192.168.1.3
then you will have to forward http port 80 from router to 192.168.1.3

so any web request will go to web server

I understand the answers thanks..yet what I am now confused about is that I already have a static ip which is external 173.9.41.202 yet when I look at the example at Port Forwarding.com the example page for my router: smc8014 asks that you input the lan ip: I have a wireless router also connected ; should I create a static ip there instead? how does this work?

The static ip points to your public device. This is usually a router. The router needed to know which private ip address to forward the internet request to. So you will tell the router to send all http traffic (80) to my web server (10.0.0.2).

Does that help?

ok
your router is connected to your ISP is not it ??

suppose your public ip is : 88.33.44.55

the ip of your router is 192.162.1.1
and your internal network is from 192.168.1.2.......

you have configured your router is not it ?? so other pc is getting ip from router , right ??

now why you want to port forward ?? what your purpose ??

the reason I want to forward the port is becuase I made a bet with someone that I could set up my computer as a dns server.... so that is why ; so far I am losing...;
anyways my static ip is 173.9.41.202/external 173.9.41.201...internal :
my lan ip (the router from comcast) is 10.1.10.1
my wireless is 192.168.0.1;
I understand that the information coming from the outside world has to go through my ports and therefore it has to go through comcast dns servers; through the comcast router (smc8014): through the wireless router: to the server;....
now when I use sysinstall to set up the internet connection and use dhcp it uses wp.comcast.net as the domain and gateway as 192.168.0.1 and also the name server as 192.168.0.1: if I try to set it up with the static ip I got from comcast the 173.9.41.202 for gateway and the comcaset dns servers 68.87.71.226, I lose internet connection...

what happened to you guys..?

hold on!! i am confused about your setup

let me explain what i understood

isp -> comcastdns server -> router -> internal pc ??

and also : with this setup  "now when I use sysinstall to set up the internet connection and use dhcp it uses wp.comcast.net as the domain and gateway as 192.168.0.1 and also the name server as 192.168.0.1: "

so what the ip of your server ?? from router do port forward to that ip which would be udp and tcp 53

but whats this comcstdns server ?? is this router aswell ??

hahah dont worry, will be with you till your problem is solved!!!

dear fosuietc... please dont assume I know what I am talking about...but let me try to explain.

comcast server (I called it dns but the wan ip address is 71.234.226.200 / and wan gateway is 71.234.224.1 )  -> comcast router in my office is i think 10.1.10.1 as the dedualt gateway to my wirless -> wirless is 192.168.0.1 ...

my staticip block is 173.9.41.202/ 30 (I guess 30 addresses is what they gave me) starting with 201..

Can you not connect the ISP line to your router directly ??
so you can simplify your network like this

isp -router- internal network

ok so you have 2 router ,

one is comcast router and another one is wireless router

and your internal pc is connect to the wireless right ??

yes that is correct..

ok then you will have to make sure port forwarding options is available for both router

from comcast router  : you will have port forward to the ip of your wireless router

you will have to port forward (tcp + udp ) for port 53  = dns port
                         tpc  for 80 = web request

now again from wireless router you will have to portforward to your server ,
same port again

does this make sense ??

Whats up have you tryed as i said before ??

to get effective solution try to response quickly
let me know

thanks I will try it but for now I am away from the machine..

Do you think that if I set up a serve I should connect the server directly to the comcast router and then from the server connect the second router for the other computers in office....is this how its usually done..???

hi sorry due to night i had to logg off

anyway
best solution s :

isp->comcast->your server-> from your server->other router


                 

so I think I understand the following:

I have static ip address which is the address the world sees: 173.9.41.202 (wan inernet ip address) this is my gateway...

this address then is the same as the first internal address which is : 10.1.10.1 (at least same in terms of what happens inside the router.

so when I port forward I have to tell the port forwarder to use 10.1.10.x    x as some number under 199

this is with the wirless router after the server....

thanks again I am going to open a new question to set up my system: yet I am directly connected to the internet with 10.1.10.12 so I have to set up sysinstall appropriately and bind so look out for my questions...

Sent me a link of your questions here
today EE Filtering is not working so i might not get your questions.
