I dont mess with DSL networks much,usually larger hub and switch side.

At Home I want to setup My Fedora 8 webserver. Works fine on private network side of second NIC. Primary Nic going to DSL modem (Zhone brand modem). it appears to see outside IP. I was wanting to check ip forwarding and other possible settings in modem first b4 calling my ISP about their port settings.I have a dynamic IP, but I monitor IP changes.Any direction on this . Thanks !!

Not farmiliar with your modem/router, but all you need to do is setup a port forwarding(or Virtual Server) in your router to point all inbound connections from the WAN on port80 to your server. You will need to setup the server to have a fixed IP within your LANs subnet.

As your ISP uses dynamic IP assignment you can either see if they offer a staticIP or you can use a service like www.dyndns.com with this an client app that you run on your lan will check your IP and notify DNS servers of the change. Some routers have the client service builtin saving you from having to run a client on a pc on your network. The basic dyndns service is free.

I did setup with dyndns and I setup ip notifier to keep eye ip changes. just cant get through ports.I did notice in another topic the ipforward website which had My modem listed. When i get to the server tonight I will try to resolve with steps. Thanks !

Page 3-25 and 3-26 explain Port forwarding, you would probably want to configure a server type port forwarding and just ensure that TCP on port 80 is forwarded to your server. Obviously your server will need to have a fixed LAN IP rather than DHCP, beyond that is there more, normally these things just work as advertised.

well,My brand and model are in earlier post.

I found out My ISP is using the DSL modem with 'bridging' option. I modified the internal LAN settings.even the dhcp setting in modem.will connect to modem and FC8 server .But,when I do this I lose outside WAN and internet. tried several steps. I'm sure I just need to find proper combination.

I'm working on new project from My house which has DSL. DSL modem/router/bridge.Ive changed LAN settings and port settings.can see modem and My FC8 server,but cant see outside or internet. reset modem to square one and internet works. anyone that can help explain or give some steps with the bridging. I'm not use to DSL. Mostly T1 or larger and usually dont deal with router side at work.
Modem is Zhone-Paradyne 6381-A3-200 ADSL2+ /R Bridge/Router.
Eth0=My network
Eth2= ISP modem side

From outside internet or DYNDNS,com:

An attempted connection to 207.144.135.22:80 was refused. This typically indicates that there are no services available on that port, but that it is NOT being blocked by a firewall or your ISP.

Try again

dyndns.com is seeing My external IP as 207.144.135.22
n reference to router side:

eth2 ( server NIC )is connected to router....

If eth2 is set to dhcp mode.the router assigns the 192.168.41.##
and I can get internet.

if I set static ip for eth2 to say maybe 192.168.1.11 (.2-.10 reserved for router DHCP . I get no internet, but i can access router(192.168.1.1) login and setup.

eth0 is private network NIC.

So if I read you correctly your modem has been setup in bridging mode, if thats the case then any routing function of the modem is disabled. I assume the ISP gave you a static IP address that you must set in your PC not your router.

If this is the case then you will need to implement another router with the WAN port set to the ISP supplied IP and then setup the forwarding in that new router.

Okay,sorry,

My ISP came in plugged up Modem and I got internet. TI never at moment requested static IP. From modem setup I don't now how to see outside ip other that my side shows 192.168.1.1 as th gateway which I know is private network IP.

I have a ip monitor working on my internal network laptop(ms winXP) which gives Me external IP.

Router does change My ip addy when I have server setup for DHCP. My ISP from what I heard from others will charge more for static IP.

If I can work around this would be good, but I wanted to see if I am missing something on router/modem before I go static.

I did setup My domain with DYNDNS.com to try to work with my changing IP.

Does not sound like bridging mode. If you go into the router inteface and New connection setup (not to change it but to see how its configured) what does it appear to be configured as PPPoE, PPPoA, Static, IPoE, Bridging?

OK, in bridging mode your PC is either allocated a static IP address or as it would appear in your case assigned via DHCP. I assume that only one address can be offered, ie if you put more than one PC on the modem (via a switch) only one will get internet access, however they may allow more but I doubt it, you need to check with your ISP.

It is also possible that unless you ask for a static IP your ISPs routers will not pass inbound requests (ie port forward)
hence you cannot initiate inbound requests from the outside internet to your server. I suggest that you talk to your ISP.

In the very least to get more than one PC on your network access to the internet you will most likely need a NAT router with DHCP enabled on the WAN port, you may also need to ask for a static IP and ensure that the ISP will forward inbound traffic to you on certain ports.

Dunno if I can help more at this point.

okay,
Here is the deal. I am using My linux server as firewall for private network and switch hub. I have a dedicated Network card for the modem.I got My static ip and setup my info in server nic that goes to DSL modem.Not seeing internet now. tried back on dhcp mode NIC goes out to internet. I called ISP tech support, We went through resets and power cycling modem and computers .

We tried straight to modem once with server ,then with laptop.. Could not even get laptop to internet with static or even dhcp,even after power recycle.

modem using bridge mode and tech support said I should just have to set static IP in computer NIC that goes to modem.

They issued trouble ticket for their advanced support for possibly monday.

any more suggestions?

Thanks!

Hi Clay, I dont think I can help you anymore, sounds like your ISP advance team need to sort some things for you. I presume you have some NAT routing rules for your NIX box to route from one NIC to other. Regarless if you cannot see the internet from that PC on that NIC then nothing is going anywhere till thats resolved.

Best of luck.

Okay,

Iv'e been on line with ISP tech support a few times they even gave me different 'static IP'. apparently it is some setting we are missing on the modem. They're using bridge mode and said I should put 'static IP' in computer,We had no luck. They are going to look at manual on My model modem and see what features need to be changed to work in bridge mode and let it through.modem and PC seem to work,and modem appears to not be communicating when we change to static. seems the dhcp option will get out and shows me further down their network than should (external IP shows their side of network where it shouldn't). So they think must be certain advanced setting in modem that needs to be switched on/off. Modem is Zhone-Paradyne 6381-A3-200 ADSL2+ /R Bridge/Router.

Keep in mind they said modem should be bridged / and static IP be in PC nic.... and should work....
but we are still trying.......
