Re: Problem connecting with ADSL modem [ was Re: Hello List ]

  That didn't work.
  I could ping my external IP 80.227.249.79 but not others.
  Error messages on first screen of main server saying that IP wasn't valid.
 
 Please, I can't see your screen, I can't see what you are trying to do
 or what you are actually doing, and I can't see the output you get. If
 there is no output, try add verbose flags '-v' and run dhclient in the
 forground with '-d'. Check your logs, see if changes has been applied,
 what is your ip after you ran the command? check with ifconfig.
 
 See the man pages for the commands you run, there may be addtional flags
 that will print extra usefull information.
 
  Now I can't ssh across the internal network to it either.
 
 From where to where, what has been working? Are your cables attached to
 the correct interfaces? if running dhclient on your external interface
 changes anything on your internal network then a) you have switched
 cables or b) indicated the wrong interfaces in previous post or c)
 things were working in the first place, and I have absolutely no idea of
 what problem you are trying to solve.
 
 Please be patient and take your time to provide usefull and correct
 information - from my end of the Internet, I can ping 80.229.247.29
 (prev. mail) but not 80.227.249.79.
 
 Fill out the diagram with interface names, ip and netmask of each
 component ad a ? if you don't have it. Provide the info from your ISP:
 your static ip, netmask, default router/gateway.
 
 If you want others to help you need to help them help you by providing
 detailed, relevant and correct information - otherwise they may just
 loose interest.

I'm trying!
80.229.247.29 is my static IP and also my default gateway.

1st: There is a typo in the diagram, you can't have the same IP as your
ISP. If this is indeed the case then this might explain things such as
why your server say it's invalid. Where in the diagram is 80.229.247.29?

2nd: The default router is the address where you send your traffic to
hosts that are not directly on your network. If you set this to yourself
then all traffic you send to the Internet newer leave your box.

On your BSD box default router should be the ip of your ISP. This is
normally set automatically by dhclient, or provided by your ISP to type in.

Just jo eliminate any confusion, since your network config has been
changed by running 'dhclient rl0', provide output from the following
commands:

# ifconfig -a
# route -v get default
# ping defaultrouter
# arp -a

defaultrouter should be shown by the route command. ping will try to
ping the router, alternatively you can try 'arping defaultrouter'
which will work even if ping is blocked (if you have arping installed).

and also,

# grep dhclient /var/log/messages

(you may remove redundant information, but besure to include the last
entries).

Check that dhclient is running. Stop it and run 'dhclient rl0' again and
see if things are any different. If so, send the changes also.

Cheers, Erik
