Sorry to report, but eh... the patch makes it worse: now the output
address seems to not change at all; it seems that the ports change, but
not the address:
(just picked some random stuff from tcpdump):

18:31:36.404755 192.168.112.10.61003 > 193.0.14.129.53: 55411 A? sander.

(24)
18:31:36.405069 192.168.112.10.61003 > 202.12.27.33.53: 56358 A? sander.

(this is from a dump at one of the outside world interfaces; as you see
the ports seem masq'd but the source address is not). (BTW, the above
dump is while only *one* output is active, so no ppp-link, and just one
rule that masq's '-s 192.168.112.0/24')

Oh, I had "sonar" from the xscreensaver distribution running and that
started showing dots again, so the ICMP stuff seems right.

Is this enough to eh... (well, spoil your weekend? I'm not sure...)? If
you need additional info, please tell me, as I'll gladly run extra
tests.

Best regards, thanks again for having ack'd my bug :-)

Valentijn
