[lug] PPP server is driving me nuts!

[Jarosko, Bill]

Actually, I think your issue arises becouse you assign a non routable IP on Dial-up client, so you are going to have to use MASQ'ing on both machines.  If there was a public IP assigned to the Dial-up client, you would be able to just use forwarding on the dial-up server.

Hello,


Setup:

Internet DSL  --- | Firewall | -----| PPP Dialup server |
                                                    | ppp0
                                                    |
                                                 dialup line
                                                    |
                                           | Dialup client |  ( W98 )

dialup connection is fine, can ping Dialup client <-> Dialup server but nothing
beyond.

Internet/lug archive search give as a result that IP_FORWARD needs to be 
enabled on the
dialup server..

As far as I can see, it is - at least in /proc/sys/net/ipv4/ip_forward is 1 
and the (SuSE ) rc.config has the IP_FORWARD=yes, got rebooted and the 
machine has done masquerading before, so it's in the kernel. But it's NOT 
WORKING!!

Only if I run the masq script it works and I can access the internet from 
the dialup client.

ipchains -P forward DENY
ipchains -A forward -s 192.168.0.0/255.255.255.0 -j MASQ

But essentially, I do double masquerading with this - once in the firewall, 
and the second time in the Dialup server - I DON'T WANT TO!!!

Could somebody please tell me how I would know if ip_forward is enabled or 
how to run the
ipchains command to enable ip_forward without doing MASQ if it's necessary?


Thanks,

Samartha
