Hi All

Can anyone explain why a machine on 10.0.0.10/24 would try and
communicate with another machine 10.0.0.4/24 via a router?
Mar  1 14:19:37 firefly kernel: DROP FORWARD INTERNAL: IN=eth2 OUT=eth2
SRC=10.0.0.10 DST=10.0.0.4 LEN=48 TOS=0x00 PREC=0x00 TTL=127 ID=17562 DF
PROTO=TCP SPT=4601 DPT=159 WINDOW=64240 RES=0x00 SYN URGP=0

SRC=10.0.0.10 DST=10.0.0.4 LEN=48 TOS=0x00 PREC=0x00 TTL=127 ID=17563 DF
PROTO=TCP SPT=4602 DPT=158 WINDOW=64240 RES=0x00 SYN URGP=0
Mar  1 14:19:40 firefly kernel: DROP FORWARD INTERNAL: IN=eth2 OUT=eth2
SRC=10.0.0.10 DST=10.0.0.4 LEN=48 TOS=0x00 PREC=0x00 TTL=127 ID=17593 DF
PROTO=TCP SPT=4601 DPT=159 WINDOW=64240 RES=0x00 SYN URGP=0

What is this? Port 158 and 159 apparently belong to
BackupExec/NetBackup. 10.0.0.10 is our backup server, but why does it
try and talk to 10.0.0.4 via the default router?
