d1d3cd65a8 [package] firewall:
- introduce per-section "option enabled" which defaults to "1" - useful to disable rules or zones without having to delete them
	- annotate default traffic rules with names
	- bump version

534feb8c9b [package] firewall:
- 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

244b5fcbdb [PATCH] firewall: provide examples of ssh port relocation on firewall and 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.

1907e1587a disable the MSS fixup hack by default (most ISPs don't require this as a workaround for MTU problems, only some do). this should give a nice speedup for routing on standard-compliant ISPs
