Ooops, PASV was the solution for that. Existing bookmarks weren’t changed with the preference. Sorry for the OT, thought better than to leave inaccurate info.

Spoke too soon on turning SPI firewall off. Although it solves ichat audio, it breaks connecting through my ftp client (Transmit), makes no difference if PASV mode is on.

With a Netgear WGR614 v6, after a full day of reading + testing tons of different configurations, the info here of turning the SPI firewall off, in combination with the port triggering list on many sites, was the final thing that did work for me (since I did want to keep DHCP IPs on the machines, + use port triggering for flexibility for more than one machine). Thanks!

well, if your computer is secure enough to connect it directly to the internet, which a Mac usually is, I don’t see any issues with uPnP. Of course the situation is different if there are also potentially malware-infested Windows machine behind the same router.

Thanks for the link, Alastair. Is that truly as serious as it sounds?

I was going to enable UPnP on my router until I read this. My takeaway is: learn to live with manual port forwarding.

You’re welcome. I wouldn’t hold my breath though for Netgear to update their router. Usually, vendors fix only the inevitable; features get added only in new products. This is unfortunate, but makes perfect business sense.

Thanks for the great tip! Unfortunately, the Netgear FVS338 (one of their high-performance “business-class” VPN routers) doesn’t support UPnP. I continue to hold out hope that Netgear will remedy this.
