Source address filtering problem

[ujemvi]

Hello! I' m having trouble with a firewall policy. Here' s my config:

config firewall vip
     edit " 100.100.100.100" 
         set extip 100.100.100.100
         set extintf " wan1" 
         set mappedip 10.1.250.135
     next
 end
 
 config firewall address
 	edit " Crossfone-1-ALT" 
         set subnet 66.66.66.64 255.255.255.240
     next
 end
 	
 config firewall policy
 	edit 103
         set srcintf " wan1" 
         set dstintf " port1" 
         set srcaddr " Crossfone-1-ALT" 
         set dstaddr " 100.100.100.100" 
         set action accept
         set schedule " always" 
         set service " SIP"  " RTP"  " PING" 
         set logtraffic all
     next
 end
 	

Now, let me show you my session log for policy 103.

So, the red line in the log. Why? Please help me to understand why is that traffic passing my policy.
