  • 1.  Routing issue with SRX100

    Posted 01-28-2013 06:33

    I am using SRX100 FW with two ISP connection.

    I have configured default route pointing to 1st ISP with qualified next hop as 2nd ISP and vice versa for 2nd ISP.

    But when I am trying to access some hosted applications on 2nd ISP it will not work until I unplug the 1st ISP.

    Please help me as I am new to Juniper.

    Hi

     

    Are you asking about traffic entering your network via 2nd ISP? Are you doing some form of NAT?

    Your problem is probarbly due to reverse route lookup that is happening for this traffic: for sessions entering via the second ISP, the reverse route (your main default) is pointing to 1st ISP which causes traffic to drop (either at session setup, or later). Generally, in such cases the solution is to put second uplink into separate virtual router. Here is an example

    If it doesn't answer your question can you please show your config and your network diagram.
