As additional information to my last and quoted message, I found
that
a) When calling a remote Linux System, PPP link uses two IP
address of the same network. Example:
After a PPP connection from my system to a remote PPP box
I got this configuration:
local IP address: 192.168.193.2
remote IP address: 192.168.193.1
ping to 192.168.193.1 works fine
b) When calling a remote PPP Server, PPP link uses two IP
address of different network. Example:
After a PPP connection from my system to a remote PPP NT server
I got this configuration:
local IP address: 192.168.75.30
remote IP address 192.168.165.8
ping to 192.168.75.30 works fine
ping to 192.168.165.8 doesn't
Any idea about ??
Thanks
Hello,
Still configuring a Linux Dial-out box on a ipchains system.
Used system: Linux 2.2.18 RedHat 6.2
Connecting a Linux PPP Server
Works fine.
Connecting a PPP Server used as router to reach Linux system
on local LAN
Means:
<--- My LAN ----> My Dial-out box ----> Other PPP Server ---> Linux System
Assume Other PPP Server is correctly configured, means has the routes
to reach any system on My LAN as well as the default route for
Linux System is Other PPP Server
Connection goeas well, even for those Other PPP Server using PAP.
Problem is I can't ping Other PP Server nor Linux System.
This is my ipchains status:
# ipchains -L -v
Chain input (policy ACCEPT: 1344758 packets, 420583373 bytes):
Chain forward (policy DENY: 625 packets, 72407 bytes):

Problem is my request to 142.1.0.4 is going out using the Default Gateway
of My Dial-out box rather than using ppp0 connection.
Are there some other tools providing more detailed information as
traceroute ?
Any idea ?
Thanks
