Yeah I know. Unfortunately the modem/router brand is not in there.
To make things worse, the model seems to be a one off - ready made for my ISP, as the only references I see to it are on sites where ppl complain about the crappy portforwarding support by my ISP.
Brand:
ArcadyanModel: 7519 (notice how you won't even find it on Arcadyan's website - the one that comes close to it in looks is the 7510)
Thanks for thinking with me though!
Another plan of action is to mail/phone Arcadyan directly. Maybe they are more forthcoming with port forwarding support (as my ISP 'officially doesnt support it'
)
