* [package] firewall: refine default ICMPv6 rules to better conform with ↵Jo-Philipp Wich2011-06-301-13/+2
| | | | | | RFC4890, do not forward link local ICMP message types, allow parameter problem git-svn-id: svn://svn.openwrt.org/openwrt/trunk@27321 3c298f89-4303-0410-b956-a3cf2f4a3e73
* [package] firewall:Jo-Philipp Wich2011-06-301-17/+44
| | | | | | | | | | | | | - allow multiple ports, protocols, macs, icmp types per rule - implement "limit" and "limit_burst" options for rules - implement "extra" option to rules and redirects for passing arbritary flags to iptables - implement negations for "src_port", "dest_port", "src_dport", "src_mac", "proto" and "icmp_type" options - allow wildcard (*) "src" and "dest" options in rules to allow specifying "any" source or destination - validate symbolic icmp-type names against the selected iptables binary - properly handle forwarded ICMPv6 traffic in the default configuration git-svn-id: svn://svn.openwrt.org/openwrt/trunk@27317 3c298f89-4303-0410-b956-a3cf2f4a3e73

* [PATCH] firewall: provide examples of ssh port relocation on firewall and ↵Jo-Philipp Wich2011-05-021-0/+22
| | | | | | | | | | | | | | | | IPsec passthrough Two examples of potentially useful configurations (commented out, of course): (a) map the ssh service running on the firewall to 22001 externally, without modifying the configuration of the daemon itself. this allows port 22 on the WAN side to then be port-forwarded to a LAN-based machine if desired, or if not, simply obscures the port from external attack. (b) allow IPsec/ESP and ISAKMP (UDP-based key exchange) to happen by default. useful for most modern VPN clients you might have on your WAN.
