hi, we are working with some tools based on rpc (such as nfs, legato, stornext ....). the authorisation based on ports forces us to open the firewall for huge port-ranges. but there are only a few known rpc programnumbers, which are linked to the right rpc-servers. i am wondering if i could configure netfilter using these programnumbers? are there already features in the core or extensions? could look like <iptables -A INPUT -p rpc --pgmnum 1073741827 -j ACCEPT> thanks have fun juerg
