hello, my name is Denny. I am new in this list.
I am trying use multiple uplinks as describe in the lartc
documentation (http://lartc.org/howto/lartc.rpdb.multiple-links.html)
with squid transparent proxy in my gateway server.
let me draw the configuration :
/-----------------
-----DSL1-----| \
|Transparent proxy |----Local network
-----DSL2-----| /
\-----------------
IP DSL1 : 172.17.1.2/30
IP DSL2 : 172.18.1.2/30
IP eth1(DSL1) : 172.17.1.1/30
IP eth2(DSL2) : 172.18.1.1/30
Local network : 10.14.1.0/24
each DSL links rate is 384 kbps downlink and 128 kbps uplinks.
my ip route setting :
------------
ip route add equalize scope global \
nexthop via 172.17.1.2 dev eth1 weight 1 \
nexthop via 172.18.1.2 dev eth2 weight 1
------------
my iptables setting :
------------
# proxy redirect
iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 3128
# postrouting
iptables -t nat -A POSTROUTING -j SNAT -o eth1 --to-source 172.17.1.1
iptables -t nat -A POSTROUTING -j SNAT -o eth2 --to-source 172.18.1.1
------------
squid config :
------------
visible_hostname my_isp.net
icp_port 0
hierarchy_stoplist cgi-bin ?
acl QUERY urlpath_regex cgi-bin \?
no_cache deny QUERY
http_port 3128

All Configuration is works. I can browsing most website.
But, I have another problem when implementing this multiple uplinks methods.
1. Messenger tools like YM will disconnect and try to reconnect every
3-5 minutes. it's always happens.
2. HTTPS for hotmail/msn is always error. "The connection was reset"
always appear in mozilla firefox. but, it never happens with
yahoo-mail and gmail (https).
3. MSN messenger never connect successfully.
All these problem never happens when I used conventional routing with
only one gateway.
After search articles in internet, I am trying to mark each connection
for MSN messenger via only one gateway. this is my solve using
iptables :
----------
iptables -t mangle -A PREROUTING -p tcp --dport 443 -j MARK --set-mark 0x10
iptables -t mangle -A PREROUTING -p tcp --dport 1863:1864 -j MARK
--set-mark 0x10
iptables -t nat -A POSTROUTING -m mark --mark 0x10 -j SNAT -o eth1
--to-source 172.17.1.2
----------
It works!! My MSN messenger is able to connect now. but always
disconnect every 3-5 minutes.
The same way I try to fix my YM problem. I trying to mark YM port and
postrouting the traffic to eth1. but, it's not solve my problem. YM
always connect/disconnect every 5 minutes. (problem number 1)
Another problem, why MSN/Hotmail webmail always refuse my connection?
(problem number 2)
Maybe somebody have idea how to solve this problem? I feel will give
up soon... :(
thanks alot for your information and helps.. :)
best regards,
Denny Zulfikar

I ran into this issue too, what I did for IM clients was run the dante
socks server and had my lan clients configure to use the proxy server to
connect. As for ssl, try marking every packet as it comes in and reroute
it out over the same interface it came in on, that way the sessions will
stay persistent over a single interface
