Access over Internet.

I'm using Asus router ac-68u (tm-ac1900) as server and I wanted to use your program for my ilok and cubase dongle
I installed linux Server app in the router, and it works perfectly in internal network. (Thank you for your great work!!)

But How can I use it over internet?
I opened TCP 7575 port of my router (server), and as I'm using asus ddns, I put the address ( in specify hubs menu of client.
Then, a message saying 'Connecting to hubs' appeared, but soon disappeared (again and again).

At first, I thought It is problem of hotspot, because I used hotspot of my Iphone to test over-internet access other than through my router. However, It turned out to be other network problem as it didn't work and same problem happened in my friend's house.

What did I do wrong?
Do I have to use VPN?

I'm going to buy license as soon as this problem is solved.


I tunred off my firewall of my router, and it works.
But is it only way?
turning off firewall
Reverse connections?
Both are not that..good..

You dont need to turn off

You dont need to turn off your firewall, you just need to allow port 7575 in/out

Found the way

I put some script to exclude firewall.
Please Let others know

1) nano -w /jffs/scripts/firewall-start

2) change the script like below
iptables -I INPUT -p tcp --destination-port 7575-j ACCEPT

ctrl+o, enter, ctrl+x

3) chmod a+rx /jffs/scripts/firewall-start
4) /jffs/scripts/firewall-start
5) and restart vhusbdarm



Thanks! thats a big help

Firewall stopping remote access

Hi Micheal,

Would there be a similar solution for Raspberry Pi? Im having the same issues as sjun3.




Probably you just need to open tcp port 7575 in your router and port forward that to your pi internal IP. if you want to access virtualhere remotely
