It's "--dports" not "--dport".
iptables -I INPUT -i eth0 -p tcp -m multiport 7777,2106 -j ACCEPT
Again, --dports is missing.
If it's the same packets you're wanting to accept, you're in the wrong
chain. INPUT won't see these; the DNAT changes the destination to
192.168.1.2. This rule needs to be in FORWARD, not INPUT.
iptables -I FORWARD -i eth0 -d 192.168.1.2 -p tcp -m multiport \
--dports 7777,2106 -j ACCEPT
