I have ssg320m..i have 2 ISP.. ISP 1 & ISP2.. ISP1 for mailing & ISP2 for internet browsing..
For this scenario i configured one default route for my ISP2 & create PBR for mail traffic on ISP1..
So i am doing internet browsing ONLY through ISP2..
Now i want internet browsing through BOTH ISP's.. but mail traffice through ISP1..
So is it possible to do the same.. if yes then how can i do the this..
Pls anyone guide me..

This is possible by configuring ECMP.
Network > Routing > Virtual Router > Edit
Maximum ECMP Routes --- <Select 2>
Configure 2 default routes with equal pref and Metric through both the ISPs.
However the above solution may cause issues for "Https" websites. I would recommend adding a PBR to send HTTPs (port 443) traffic through any one of the ISPs.

Thanks for your suggestion..
Pls confirm one thing.. that your suggested configuration will not effect my SMTP traffice which is going through ONLY ISP1 through PBR....
becouse i dont want my smtp traffice pass through my ISP2...

Again thanks Sarab..
One more question..In this senario how do i know that which user's internet traffic passing through which ISP..
Can i do command over this through DNS of my ISP..means suppose when i put ISP1 DNS on PC1 then its internet traffic go through ISP1 and when i put ISP2 DNS on PC2 then its internet traffice go through ISP2..
And how can i block any website through SSG320M..

I have configured ECMP as adviced by you but when i am giving ISP2 DNS IP to user then internet browsing working fine & when i am giving ISP1 DNS IP to user then internet browsing becomes very slow...OR some times users are not able to open any website..
PLEASE advice where is the issue..

I am not able to ping ISP1 DNS form juniper firewall but able to ping ISP2 DNS..Trace route of ISP1 DNS is also not successful..... below is my DNS configuratin
DNS .> Host > dns1 - 202.X.50.4 src int. Eth0/2 -----(ITs my ISP1 DNS)
dns2 - 202.X.230.5 src int. Sth0/3 -----(its my ISp2 DNS)
Is there any issue..
You advice to configure global DNS... pls suggest how to configure the same...
