 'reply-to'

 I changed the rule to use 'route-to' instead of 'reply-to' and the
 ICMP storm stopped.
 
 ----------
 if_isp1="em0"
 isp1_router="GW1.GW1.GW1.GW1"
 if_isp2="em1"
 isp2_router="GW2.GW2.GW2.GW2"
 
 pass in all no state
 pass out all
 pass out route-to ( $if_isp1 $isp1_router ) from $if_isp1
 pass out route-to ( $if_isp2 $isp2_router ) from $if_isp2
 ----------
 
 I'm not sure about the implementation difference of 'reply-to' and
 'route-to'.
