   /proc/sys/net/ipv4/ip_forward = 0

This is never going to work until you enable ipv4 forwarding
(IP_FORWARDING=Yes in shorewall.conf). There are also these log messages:

Oct 20 14:41:26 FORWARD:REJECT:IN=eth0 OUT=eth0 SRC=143.129.75.57
DST=143.169.254.100 LEN=74 TOS=0x00 PREC=0x00 TTL=254 ID=12911 PROTO=UDP
SPT=63863 DPT=53 LEN=54

Hopefully, those were created when you still had a default gateway
specified for eth2?

The system is gratuitously adding this route:

  169.254.0.0/16 dev eth2  scope link  metric 1000

So broadcasts received from 169.254.0.0/16 on eth0 are considered
martians. That is why you are seeing these messages.

  martian source 255.255.255.255 from 169.254.34.236, on dev eth0

Either delete the route or disable martian logging.
