I'm using Satori 4 and getting to the Linksys with a telnet session. I just want to block an address range (a class C). I can get the iptables rule in there, but if I open the Linksys web management page, it removes the entry. I'm doing it like this: (none):[~]# iptables -A INPUT -s 22.214.171.124/24 -j DROP (none):[~]# nvram committ nvram_commit(): start nvram_commit(): end (none):[~]# iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination logdrop all -- anywhere anywhere state INVALID ACCEPT all -- anywhere anywhere state RELATED,EST LISHED ACCEPT all -- anywhere anywhere state NEW ACCEPT all -- anywhere anywhere state NEW DROP icmp -- anywhere anywhere DROP all -- anywhere anywhere DROP all -- 126.96.36.199/24 anywhere If I open the Linksys web management page, change anything (or nothing) and save, it clears my entry. I cant figure out how to enter a firewall rule from the web page cmd box either. It wont recognize ipchains. Thanks in advance for any help.
