How to forward ports for X11 on Proxmox to a MV

[z3nth10n]

Well, I read that I needed to open ports 6000-6063 and also 117 (UDP).

I tried it without luck:

post-up iptables -t nat -A PREROUTING -i vmbr0 -p tcp --dport 6000:6063 -j DNAT --to 192.168.x.xxx:6000-6063
        post-down iptables -t nat -D PREROUTING -i vmbr0 -p tcp --dport 6000:6063 -j DNAT --to 192.168.x.xxx:6000-6063
        post-up iptables -t nat -A PREROUTING -i vmbr0 -p udp --dport 117 -j DNAT --to 192.168.x.xxx:117
        post-down iptables -t nat -D PREROUTING -i vmbr0 -p udp --dport 117 -j DNAT --to 192.168.x.xxx:117

Under my client, I execute:

ssh -Y -p xxxx root@my.ip.com

But I get this when I try to execute gedit:



I suppose the problem is related to port forwarding issues. But I can't figure it out.

I already check iptables-save but everything is OK, so Idk what's going on.

Thanks!

Hi,

Is the X11Forwarding enabled on your ssh config?
what the output of: cat /etc/ssh/sshd_config| grep X11Forwarding

Hi,

thanks for your response!

I have it enabled, I also tired using

export DISPLAY=:0
export DISPLAY=0

But none worked...

 

[Moayad]

could you try with -X flag, ssh -X root@my.ip.com
