yes, it may be reporting a transparent proxy address, some of the 'detect
ip' sites are pretty good at detecting proxies but the ISP seems to be doing
a reasonably good job in this case.

I'd have to suggest there's no real corelation between ISP's implementing
transparent proxies and those blocking ports, but I've been wrong before.
