Hi, as far as I understood, I am a newbie, but vmbr0 (linux bridge) should have all the configuration that you configured in enp5s0f0 and port slaves should have configured only enp5s0f0.

Hello,
did you install the Proxmox host yourself or is this a dedicated server with pre-configured settings? You seem to have a public IP address there.
A configuration like in your screenshot indicates that there is (should be) a NAT-Setup between your vmbr0 and enp5s0f0 interfaces, but the GUI won't give us enough information. Can you post the content of your
Oh, and try to mask your public IP (XXX.XXX.XXX.151/26), because you never know who else reads this public forum.
Kind regards,

You are right, but that is good only for a basic Proxmox configuration (like, inside your LAN). This server is reachable from the internet, so we need a bit more configuration here. (else the VMs connected to vmbr0 too need - expensive - public IP adresses).

Well then I suggest you use a classic Masquerading setup:
You then connect your VM to the bridge vmbr0 and give it a static IP in the 10.10.10.0/24 subnet, like 10.10.10.2 with Gateway 10.10.10.1 and a DNS server like 8.8.8.8
Do note that Proxmox does not come with a DHCP server, so you can't just assume that your VMs automatically get a IP address.
Code:
auto lo
iface lo inet loopback
auto enp5s0f0
#real IP address
iface enp5s0f0 inet static
address XXX.XXX.XXX.151/26
gateway XXX.XXX.XXX.129
dns-nameservers 8.8.8.8
dns-search xxxx.xxxx
iface enp5s0f1 inet manual
auto vmbr0
#private sub network
iface vmbr0 inet static
address 10.10.10.1/24
bridge-ports none
bridge-stp off
bridge-fd 0
post-up echo 1 > /proc/sys/net/ipv4/ip_forward
post-up iptables -t nat -A POSTROUTING -s '10.10.10.0/24' -o enp5s0f0 -j MASQUERADE
post-down iptables -t nat -D POSTROUTING -s '10.10.10.0/24' -o enp5s0f0 -j MASQUERADEYou then connect your VM to the bridge vmbr0 and give it a static IP in the 10.10.10.0/24 subnet, like 10.10.10.2 with Gateway 10.10.10.1 and a DNS server like 8.8.8.8

hey thanks sorry for the late reply again, so dns-search what should i put for that would google.com work or what?
EDIT: NEVERMIND

copied and pasted it in and edeted it now for my windows vps its looking like this. still not connected to the internet
this is what my /etc/network/interfaces file looks like

The interfaces-file looks good. Did you reload the network config? Just copying it in won't be enough.
Subnet mask of your Windows VM should be 255.255.0.0 since your internal network is /24. It is weird that your ipconfig yields the link-local addresses, is the network interface connected to vmbr0? What is your VM config?
You can then try to trace your path by doing pings with increasing scope from your VM:

You can then try to trace your path by doing pings with increasing scope from your VM:
- ping 10.10.10.1 (local gateway)
- ping XXX.XXX.XXX.151 (proxmox-WAN)
- ping XXX.XXX.XXX.129 (WAN-gateway)
- ping 8.8.8.8 (internet)
- ping proxmox.com (DNS-resolve & internet)
i did not reload the net conf my bad, im just gonna do a reboot cause my dedi was acting up,
From inside, so another machine in the 10.10.10.0 subnet? The connection should work already, there is nothing related to layer 4.
From outside? Then you need to set up port forwarding rules in your interfaces file. I rarely do this in Proxmox, but something like this might work for TCP/3389: (no guarantee though):

Code:
post-up iptables -A PREROUTING -t nat -i enp5s0f0 -p tcp --dport 3389 -j DNAT --to-destination 10.10.10.2:3389
post-up iptables -A POSTROUTING -t nat -p tcp -d 10.10.10.2 --dport 3389 -j MASQUERADEalso if i wanted a tcp/udp port what would i do? ex tcp/udp for 30120 & 40120, also the RDP session worked thank you so much man youve been so much help

Got the port situation working, one more thing then im all set, im trying to setup a ubuntu server, and im confused
how would i get the 10.10.10.1 subnet working?
The first field sets the subnet, not the IP address. So the right values would be
- Subnet: 10.10.10.0/24
- Address: 10.10.10.5
- Gateway: 10.10.10.1
- Name Servers: 8.8.8.8 (or what you prefer)
- Search Domain: <empty> (unless you have your own domain)
Kind regards,
