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
