* firewall: provide examples of ssh port relocation on firewall and IPsec ↵Jo-Philipp Wich2011-05-021-11/+39
| | | | | | | | | | | | | 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: prevent excessive uci state data aggregation (#9152)Jo-Philipp Wich2011-04-201-0/+2
| | | | SVN-Revision: 26740
* firewall: allow local redirection of portsJo-Philipp Wich2011-04-121-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
