Remote RDP Connection Testing

Hi people. Iam trying to do some testing for remote rdp connections. My clients connect to rdp servers running proxmox through ssh onto a another linux server and tunneling and port forwarding 3389 to the ip of the windows server on proxmox.

From the lan in the same office I get circa 28 down and 3.8mb up. If connect from the internet using ssh and port tunneling and run the same test in the windows server on proxmox I get circa 20mb down and 2.5 up? It looks like the tunnel in and subsequent connections out is casuing some sort tcp interference or bottleneck?

To improve the situation I would like to go in one connection and have the windows server intenet access out another way.

So I have two vmbr's one on the lan which I connecto via ssh and port fwd and the other vmbr1 direct connection to the internet with a public ip and gateway. I assign the vmbr1 as a nic on the virtual windows and set public ip on this also but I cannot access the net. On the other nic I remove gateway. Still no internet access. Note this done for testing purposes only.

Can any point me in the right direction? ssh in on one public ip through firewall and connect to virtual server on lan and thensaid same server has public ip to access the net.

Thanks in advance.

Hi Stephen,
should work without trouble.
How looks your network-config? ( "cat /etc/network/interfaces")

How looks your vm-config? ( "cat /etc/qemu-server/VMID.conf")

In the windows server I am just repeating the ip settings note I disable one of the wan interfaces in windows so only one in theory has public ip

Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . :

That is odd becuase I have manual entered theright public IP addresses but yet ipconfig shows a private ip 169.....

The route command on proxmox gives

default 78-105-96-1.zon 0.0.0.0 UG 0 0 0 vmbr1
default z1.invictus.lan 0.0.0.0 UG 0 0 0 vmbr0

NSLOOKUP's dont work and neitehr does apt-get update so zero access on the proxmox server.

A routing issue?

Thanks

Hi Stephen,
first - use only one default-gateway on the host!
The second part is, that you use two bridges for the same network (vmbr1+vmbr2).

And you don't need an IP-Address on each bridge - only important on vmbr0. Except you want to use the Address on the host (for nat, access, ...).

Try this config and use the IPs in the VMs:
Code: 
auto lo
iface lo inet loopback

iface eth0 inet manual

iface eth1 inet manual

iface eth2 inet manual

auto vmbr0
iface vmbr0 inet static
     address  192.168.30.2
     netmask  255.255.255.0
     gateway  192.168.30.1
     bridge_ports eth0
     bridge_stp off
     bridge_fd 0

auto vmbr1
iface vmbr1 inet static
    address 0.0.0.0
    netmask 0.0.0.0
    bridge_ports eth1
    bridge_stp off
    bridge_fd 0
