how to assign a real IP to a PPP host?

how to assign a real IP to a PPP host?

[Patrick van der Smagt]

Dear Netfilters,

I'm blocked by the following problem.  My host has two IPs on interface 0:
	12.12.12.12
	12.12.12.13
The first IP is its "real" IP on eth0:0, I created the second one to have
it assigned to a ppp-connected client machine.

To my host a second machine is connected over a ppp connection, and it
has the local IP 10.1.0.100.  What I want to do is to give the remote
machine the permanent IP 12.12.12.13.  I want all network traffic for
10.1.0.100=12.12.12.13 (and a cluster of machines behind that) to be
routed through 12.12.12.12.

I've set up iptables as follows to do what I want:
  iptables -t nat -D PREROUTING --dst 12.12.12.13 \
        -j DNAT --to-destination 10.1.0.100
  iptables -t nat -D POSTROUTING --dst 10.1.0.0/24 \
        -j DNAT --to-destination 12.12.12.13
  iptables -t nat -D OUTPUT --dst 12.12.12.13 \
        -j DNAT --to-destination 10.1.0.100
The first and second rule work fine, with those I can reach my machine
10.1.0.100 at address 12.12.12.13 from all hosts, except 12.12.12.12 (of
course). That's what the third rule is for.  However, rule 3 does not
do everything for me.  After setting up all of the above rules, when I
telnet to port 110 from .12 to .13, I receive no answer.  I find in
/proc/net/ip_conntrack on .12:

tcp      6 118 SYN_SENT src=12.12.12.13 dst=12.12.12.13 sport=2996
dport=110 [UNREPLIED] src=10.1.0.100 dst=12.12.12.13 sport=110
dport=2996 use=1

or

tcp      6 57 SYN_RECV src=12.12.12.13 dst=12.12.12.13 sport=2996
dport=110 src=10.1.0.100 dst=12.12.12.13 sport=110
dport=2996 use=1

How do I get this running??  Please help!

How will I mesure my bandwith

[Sundaram Ramasamy]

Hi,

We have 512kbps connection to our office, How will I measure my bandwidth.

I used following link, it show only 368.2kbps. Is there any other method to
test this.

Thanks
Sundaram

You could use a tool such as iptraf http://cebu.mozcom.com/riker/iptraf or 
simply check the byte counts for your external interface at regular intervals.

ifconfig eth0 | grep bytes
will tell you the number of bytes in & out of eth0 - you could set a cron job 
to do this every minute and redirect the results to a file ?

Google for bing displays lots of stuff about Mr Crosby, plus some links to 
getting the source from ftp://ftp.ibp.fr which doesn't seem to exist...

Looks like an intriguing way to measure bandwidth - I'd be interested to test 
it and see how reliable the results are - can you suggest where I can get it 
from ?

Debian has a pacakge for it, (apt-get install bing), so if you can 
install DEBs you can get it from 
http://packages.debian.org/stable/net/bing.html

Reading the README that came with, you can get new releases at 
http://www.freenix.org/reseau/outils.html

The site might be in French mind you.

If you are interested in more detailed information, my ulog-acctd
(http://savannah.nongnu.org/projects/ulog-acctd) may be the solution
for you.

You can also use a tool like MRTG that looks at the interface byte
counters on a regular basis and puts out nice graphs based on those
numbers. But AFAIK you also need a working SNMP daemon setup for that.

This is very unlikely to be a firewall problem.

What do the headers of the emails say ?   Where is the excessive delay 
occurring ?
