PPP Dialin Server...no Web browsing

By clodur ·
Hello,

I have a Redhat 9 Server configured as a PPP Dialin Server on my domain, kind of a mini-ISP. I can connect to the machine just fine from any client over the phone. My problem is that after I connect I can not browse the web. When I am connected to the server, I can only ping the PPP Server itself, nothing passed that. The IP address I receive for the client is correct as I set it in the /etc/pp/options.server.
I can access accounts only using a shell. I want to be able to use the dialin connection to access the web as I would if I was connected to a Windows 2000 RADIUS.
Here is a copy of my /etc/ppp/options.server:

-detach
asyncmap 0
netmask 255.255.255.0
modem
crtscts
lock
/dev/ttyS1 115200
require-pap
refuse-chap
login
#proxyarp
ms-dns 192.168.0.20
ms-dns 192.168.0.30
#
192.168.0.23:192.168.0.11

....keep in mind that I do connect to the server just fine, just no Web Browsing.

Can anyone please tell me what I am missing, I've been working on this for quite a while now and I can't figure out what is wrong.

Thanks in advance.

What's your client's OS?

The last client OS I tried was windows XP, I also tried to connect using Windows 2000.

Hello all!
I submitted this question about a week ago and no one out there seems to have an answer....
If any one needs to see more of the files on my Redhat 9 server, feel free to say it I will copy and paste the contents for you to see.
I'm still working on finding the answer myself, so if I find it before any one else, I will ost my findings here.
Til' then,
Thanks for trying.

I suspect that you have not configured TCP/IP forwarding on the box to allow packets from one interface (in your case the modem) to the LAN interface.

To do this in realtime enter (without quotes):
"echo 1 /proc/sys/net/ipv4/ip_forward"
This will change the value of this file from 0 to 1

To make it permanent (after reboot):
edit the file /etc/sysctl.conf
edit the line net.ipv4.ip_forward=0
change the "0" to a "1"
Save and exit

Soliver1, thanks a bunch....:)) It worked!
I had to manually edit the ip_forward file, everytime I issued the command, for some reason it never took.

Anyway, it works now, I am now able to browse the web after dialin in to the linux server.

Thanks again.

To Solivier1:
I put the line:"echo 1 /proc/sys/net/ipv4/ip_forward" into my ipchains file and edited the: /etc/sysctl.conf.
It still doesn't work..:(
Which file exactly should the "echo 1..." line be put in?
Thanks in advance... I feel something good in the making here! :)
