It's "--dports" not "--dport".

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
