- solve scoping issues when multiple values are used, thanks Daniel Dickinson
- ignore src_port/dest_port for proto icmp rules, ignore icmp_type for non-icmp rules
- properly handle icmp when proto is given in numerical form (1, 58)
- support negated icmp types

- 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

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.

Allow a redirect like:
config redirect
option src 'wan'
option dest 'lan'
option src_dport '22001'
option dest_port '22'
option proto 'tcp'
note the absence of the "dest_ip" field, meaning to terminate the connection on the firewall itself.
This patch makes three changes:
(1) moves the conntrack module into the conntrack package (but not any of the conntrack_* helpers).
(2) fixes a bug where the wrong table is used when the "dest_ip" field is absent.
(3) accepts incoming connections on the destination port on the input_ZONE table, but only for DNATted
connections.
In the above example,
ssh -p 22 root@myrouter
would fail from the outside, but:
ssh -p 22001 root@myrouter
would succeed. This is handy if:
(1) you want to avoid ssh probes on your router, or
(2) you want to redirect incoming connections on port 22 to some machine inside your firewall, but
still want to allow firewall access from outside.

- partially revert r21486, start firewall on init again
- skip iface hotplug events if base fw is not up yet
- get ifname and up state with uci_get_state() in iface setup
since the values gathered by scan_interfaces() may be outdated
when iface coldplugging happens (observed with pptp)
- ignore up state when bringing down interfaces because ifdown
reverts state vars before dispatching the iface event
- bump package revision
