Extreme Networks

hint, ipforwarding should be enabled on each vlan, not just on internetten. And what about NAT ? Does the internet router knows these IP's  ? Routing needs to be working both ways. 

btw, this is not an exos switch but extremeWare. very old and some commands might differ, although most of them are the same. Just basic routing.

Is finding the solution not part of the opdracht (assignment) ?

I would upgrade XIQ Site Engine first to 23.11 or 24.2 and check after that. 

What version of XIQ Site Engine ? Are you archiving through ssh/scp ? If your Site Engine is too old it could be a cipher issue, or your scp settings could be wrong. https://extreme-networks.my.site.com/ExtrArticleDetail?an=000111555
