It's working ok on APU1, if it's any consolation. The APU2 board I ordered burned down, so I can't check there sadly.

['Save' button does essentially nothing]

Let's say I want to forward port 5901 to my lan, but it seems that I can't enter non-standard port numbes in any of the port selection boxes.

I tried to add an alias for 5901 port, but it seems that the 'Save' button does essentially nothing.

I can work around it by directly modifying config.xml and defining the resource.

My scenario:

I have two interfaces WAN_DHCP (ethernet) and MODEM_PPP (a 3G modem) and their respective gateways configured. There is a group called UPLINK, WAN is Tier 1 and default gw, MODEM is Tier 2.

Apinger is using google DNS addresses (8.8.4.4 & 8.8.8.8 ) for failure detection.

"Allow default gateway switching" is enabled under Settings -> Miscellaneous.

LAN interface is also used.

What I want to accomplish is traffic failover (from LAN) to 3G modem in case WAN link goes down. It works pretty well when the WAN interface is up and available during router startup, but..

Problem occurs when the router boots up without link on WAN interface. For example, when router is booted up in a  location where the main (wired) connection is not available yet (but will be added on a later date).

How to reproduce:

Configure interfaces as described. Remove WAN cable before powering on the router. Power on the router.

After startup, it looks that apinger took one look at the state of things and died:

Feb 9 12:50:43    apinger: Starting Alarm Pinger, apinger(56008 )
Feb 9 12:50:43    apinger: No usable targets found, exiting

If I restart apinger from web ui, it starts up, but doesn't seem to do anything useful. No default route gets set, network traffic doesn't pass through the router. It can detect delay problems.

Feb 9 12:57:22    apinger: Starting Alarm Pinger, apinger(25102)
Feb 9 12:57:40    apinger: ALARM: MODEM_PPP(8.8.8.8 ) *** delay ***
Feb 9 12:58:15    apinger: alarm canceled: MODEM_PPP(8.8.8.8 ) *** delay ***

If I plug in the WAN cable now, everything whirs into action. Default gw gets set, traffic flows.

Feb 9 13:00:12    apinger: SIGHUP received, reloading configuration.
Feb 9 13:00:19    apinger: SIGHUP received, reloading configuration.

If I remove the WAN cable now, traffic and default route fails over to MODEM properly.

Feb 9 13:01:43    apinger: ALARM: WAN_DHCP(8.8.4.4) *** down ***

I hope this description makes sense.

Any ideas how to make anything any better?
