What is my source?
tail /var/log/messages
Dec 14 14:53:14 rama-kandra kernel: Shorewall:all2all:REJECT:IN= 
OUT=eth3 SRC=203.96.213.73 DST=203.152.118.23 LEN=288 TOS=0x00 PREC=0x00 
TTL=64 ID=73 DF PROTO=UDP SPT=500 DPT=500 LEN=268

doesn't match tcrules
4       202.37.230.93   0.0.0.0/0       udp     500

how does the kernel decide which src to use?

Ultimately I want all UDP 500 to use src 202.37.230.93
