I seriously doubt that.

Is your ISP routing 60.xxx.xxx.2 via 60.xxx.xxx.1?

Or are both addresses being routed via one of your other IP addresses?

Or does your ISP expect that both .1 and .2 will respond to ARP requests
directly from their upstream router? In that case, hopefully they can
still use the same gateway as your Shorewall box is using?

These details determine how you must configure your Shorewall system.
