[nznog] Port filtering by NZ ISPs?

Hi guys - I'm trying to conduct some penetration testing on some networking equipment and I was finding that some ports were being filtered when someone else at the company was using an **** dialup account to try some things. A call to the **** helpdesk yielded exactly the results I expected so I was hoping someone here could give a more intelligent answer. I'd really like to find out what various ISPs are filtering from dialup or other pools - please email me directly if you have anything to offer. I am happy to sign and fax back NDAs if required and the info would be used for nothing but checking against our own test results or selecting ISPs for use during testing. Cheers - Neil G
