GnatBox has the nice web based interface and easy to work with console, the
others drop this (IMHO the Edge is the least user friendly, but the easiest to
configure at the start).

The light at the end of the tunnel is an oncoming dragon.
I bought the 4-port Speedtouch Pro ADSL modem/router.
It uses PPP to talk to my ISP. It is connected to my
Linux box via the ethercard card. I will also connect a laptop
to the router, so that I will have a two-machine LAN.
(Cannot connect laptop to PC, as I have only one network card on the PC.)
The router works fine as a modem and an NAT box. But there is no firewalling on
the router as it does not seem to support port forwarding.
So, how to do firewalling?
In principle, I am thinking of:
(a) forwarding all network traffic to my PC
(b) setting up the PC as the default gateway for all other machines on the LAN,
using iptables to do the port forwarding on the PC.
Would anyone know if this is possible with the Speedtouch Pro?
There is an option on the PPP setup of the router for an "Only Me"
connection, so that the router would allow only my PC to use its ADSL connection.
I am assuming that this achieves (a).
But would the router send all packets from my laptop via my PC, if I tell my
laptop (running Win98) that the default gateway is 10.0.0.1 (private address for
my PC)? I suppose I have to do something with the IP routing table on the router.
At the moment, the table is:
Source Gateway Intf
10.0.0.1/32 22.214.171.124 MYPPP
10.0.0.0/8 10.0.0.0/8 10.0.0.138 eth0
any 126.96.36.199 MYPPP
any 10.0.0.138 eth0
10.0.0.138/32 any 10.0.0.138 eth0
10.0.0.138 is the router
10.0.0.1 is the Linux box
212.56... is my ISP-assigned IP address for my connection
