Re: 11.23 networking setup

The ip_ire_gw_probe setting is your problem. With that set to the default value of 1, the system pings the gateway periodically to see if it has died, and if it doesn't respond it stops sending traffic to it.

Set it to 0 as in the example given by Hans to avoid the problem.

You will have to either reboot or manually remove and re-add the default gateway after changing the setting. You can change it on the fly with :

ndd -set /dev/ip ip_ire_gw_probe 0

... but you need the nddconf setting to make it survive a reboot.

I think the latest Arpa Transport patches may change the behaviour such that when enabled, it reports the dead gateway on the system console but continues to send the traffic. Don't remember the exact details.

Re: 11.23 networking setup

Hello all,

I resolved this issue by installing all missing patches. I'm not sure which patch/patches specifically were responsible for fixing this issue, but network traffic can leave the local network now.

I checked prior to applying these patches and I did have installed the most recent cumulative ARPA transport patch, and all dependencies, so I am not sure it was related to that.

Thanks all for your help and your suggestions.

Re: 11.23 networking setup

Shalom John,

I recommend that at least annually, you update the system with a QPK major patch set. This will help keep your system running healthy.

QPK's are issued bi-annually.

Re: 11.23 networking setup

Sound advice. Something I will make sure to do in the future, as I see now that missing patches can cause strange behavior.

Thanks again all,
