Silknet http(s) ports blocked

[Alexey]

Hello,

I use Silknet ISP with a regular CABSAT GM203-7 as a router.

I've decided to setup my NAS recently and want to open it to the external network.

I did manage to open basically every port but 80/443 (I tried 81, 444, >1000) to the internet, but these two are closed. Does anybody know if they're blocked upstream? Or is there a setting blocking them somewhere in the router? Can I run router in bridge mode and let ports passthrough to my router (which is connected next to CABSAT)? If they're blocked upstream - did anybody manage to convince tech support to unblock the ports for an individual user?

probably silknet block those ports for security reasons, you have to call them and ask to unblock those ports, even 8080 port is blocked, you may use their router NTP Server Address: acs69.silknet.com for time sinchronization, not sure about bridging, probably ports will remain closed with another router as well, you have to call and find out if they will open closed ports, i think there's around 10 ports that silknet  blocked, probably silknet won't open them, all others you might open in router with port forwarding, including torrent clients and gaming servers

Did you get any luck asking to unblock the ports?

8080 is not blocked actually, I'm running http traffic to it through another server.

i forgot time servers is on 123 port not 8080, so it is blocked, 8080 used for  Hypertext Transfer Protocol (HTTP), if you use acs69.silknet.com it is open an time synchronisation working in windows, not sure about bridging, probably they will be blocked as well if you bridge main router, if port blocking is on isp level i think bdidge mode won't help, some other ports also blocked i think, around 10+ minimum:

but they might open them if you ask and say you don't care about security

I called Silknet and they agreed to open ports (required verification via SMS to contract owner's number).

I also asked what ports are closed (that was via phone, could be typos): 21, 22, 23, 25, 53, 69, 80, 81, 83, 85, 119, 123, 123, 139, 161, 190, 443, 445, 1070, 1900, 5001, 7547, 10001, 52869, 58000
