Hi all,
I have been having a big problem with my internal network. I am using
PPPoE. Below is my configuration file. I must say that everything
works, other than port forwarding. I only have one forwarding line, and
no matter what I have tried I cannot get it to work. Any help would be
appreciated.
# /etc/ppp/ppp.conf - beginning
#
# PPP Version 2.26 - Mar 20 2000
#
default:
set device PPPoE:dc0
set MRU 1492
set MTU 1492
set authname ********@sympatico.ca
set authkey ********
set log Phase tun command
set dial
set login
set ifaddr 10.0.0.1/0 10.0.0.2/0
add default HISADDR
set cd 5
set crtscts off
# Only added the line below so that I could use pppctl
set server /var/run/internet "" 0177
# Comments were removed when I was testing
# alias enable yes
# alias port tcp 192.168.1.21:80 80
# alias log yes
# nat enable yes
# nat port tcp 192.168.1.21:80 80
# nat log yes
papchap:
set authname ********@sympatico.ca
set authkey ********
#####
# /etc/ppp/ppp.conf - end
Please note that I tried both the alias version and the nat version to
no avail. I do have a network connection from my internal network out,
but I cannot get the port forwarding. Below is my netstat table:

I have also tried using pppctl and typing in the commands by hand, but
have had no luck. Am I missing something?
Thanks in advance for all those that try to help.
Andrew.
