shorewall problem DNAT


hi there

i was looking to correct the erros that i am doing

this is what i want to do

there are 3 machines

A- client machine
B- firewall
C -real proxy


all of them are on same network
now i have setup B as the proxy for A and at B i have used DNAT to specify to forward all requests to machine C on its proxy

i have these settings in my rules file for shorewall at B

DNAT lan lan:<ip of C>:3128 tcp

DNAT fw lan:<ip of C>:3128 tcp

the second rule which is for the firewall i.e B works fine i.e i can access the internet fine from B using B''s IP as my proxy server which forwards this to C

but other machines like A cannot connect to C wioth B's IP
they can connect if they cpecify C's IP in their proxy settings

i have the ACCEPT policy for all in my policy file

any thing that i need to check???

regards

Have you looked at /sbin/shorewall status ?

Have you looked at /sbin/shorewall status ?

Try making the connection that is failing.
#

/sbin/shorewall status > /tmp/status.txt
#

If you post the /tmp/status.txt file, someone may be able to help you.
