my final config file that works along with couple of commands you need to put

Would you mind sharing your final config as sample for others
who might need in the future?
Thanks!

Yes it was exactly this & thanks Soner Tari & Stuart Henderson for Helping
me (newbie) in so detail that now finally i have succeeded in making
multiple external connection & serving them as one.
lush it feels so good ..
Thank you.
I owe you one.
p.s is it possible to have a 3rd internet connection join this ? :)

Subject: Re: multiple external links not working ..
Hi, I'm using two external interfaces myself, and I believe I had the
same problem you describe in your message. I bet when you do:
netstat -rnf inet | grep default
you will see that your (ext_if2 ext_gw2) comes on top. Thus, my theory
is that the kernel is preferring your second external interface due to
your routing table (i.e. the order of your default routes).
Since I don't know how to handle this in pf.conf for connections
originating from my firewall, such as an http proxy running on the
firewall, just as in your case too (otherwise route-to and reply-to work
fine), I change my routing table in rc files.
Specifically, I rearrange the order of my default routes to have my
first external interface/gateway on top:
route add default -ifp ext_if1 -mpath ext_gw1
route add default -ifp ext_if2 -mpath ext_gw2
Accordingly, I removed the similar shell commands in hostname.if(5)
files.
Hope this helps,

now the main internet connection is the powerful one which i only want to
use for specific protocols which i have defined in a macro called ports
now rest is supposed to goto to my 2nd internet connection which is a weak &
cheap connection basically there to allow p2p applications access.
