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.

firewall ( #7355 ) - 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yet - get ifname and up state with uci_get_state() in iface setup since the values gathered by scan_interfaces() may be outdated when iface coldplugging happens (observed with pptp) - ignore up state when bringing down interfaces because ifdown reverts state vars before dispatching the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
