Routing

Hello, I am using an ex4200 switch as the default gateway for devices on our LAN.  On this I have a default route pointing to our FW for Internet traffic.

I am bringing a new firewall online and would like to do some testing before going live.  What i am hoping to accomplish is this;

    If the router sees a packet sourced from PC A's IP address, set the default GW to the new FW.  Otherwise use the default GW pointing towards the old firewall.  There are other routes in the routing table for our WAN and other vlans as well.

Would Filter-Based Forwarding accomplish this?  

I tried setting this up on an Olive and it didn't work as expected, but they may be a limitation of the Olive.

Thanks

Hi, 

Can you share your filter configurations...this should work in junos not sure of Olive though..

Thanks,

Dear

For FBF configuration make sure that your configuration is similar to this link

http://www.juniper.net/techpubs/software/junos/junos94/swconfig-routing/configuring-filter-based-forwarding.html#id-10890307

then configure firewall filter matches on source subnet and action routing-instance (don't forget to add term2 then accept) otherwise all traffic will be discard. Then attach this firewall filter in input direction on the LAN interface.

If your configuration similar to that could you please attached it

Thanks,

That did the trick.  I must have missed something before.  Thanks
