Setting iptables rule for all protocols for specific source and destination ports

  • 772

Is it possible to add a IPTABLES rule which allows all the protocols for specific source and destination ports? I tried the following but it didn't work.

iptables -I FORWARD 1 -s 172.27.0.254/255.255.255.255 -d 0.0.0.0/0.0.0.0 -p 0 --sport 0:65535 --dport 1191:1191 -j ACCEPT

iptables error: unknown option `--sport`

Any comments are greatly appreciated.

    You can't use --sport or --dport with -p 0 (or -p all) because IP transport layer can have protocols that aren't tied to ports. You can do this with protocols like udp/tcp/sctp/etc.
