Hi,
Am new to proxmox, one of my requirement is am want to have 4 interfaces for an instance with different network

VMbro 0 : 172.16.1.1
VMbro 1 : 10.0.0.1
VMbro 2 : 172.16.2.1
VMbro3 : 10.0.1.1

Can anyone please guide to configure the same in proxmox.

Note: I have only one interface card for proxmox server. Am running windows 10 in the intance.
 
Hi,

what do you want to do with this 4 network?
Do you have Vlan or this network internal only?
 
auto vmbr1
iface vmbr1 inet static
address 192.168.0.254
netmask 255.255.255.0
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 '192.168.0.0/24' -o vmbr0 -j MASQERADE
post-down iptables -t nat -D POSTROUTING -s '192.168.0.0/24' -o vmbr0 -j MASQERADE
post-up iptables -t nat -A POSTROUTING -i vmbr0 -p tcp --dport 1080 -j DNAT --to 192.168.0.102:80
post-down iptables -t nat -A PREROUTING -i vmbr0 -p tcp --dport 1080 -j DNAT --to 192.168.0.102:80


auto vmbr2
iface vmbr2 inet static
address 172.16.0.254
netmask 255.255.255.0
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 '172.16.0.0/24' -o vmbr0 -j MASQERADE
post-down iptables -t nat -D POSTROUTING -s '172.16.0.0/24' -o vmbr0 -j MASQERADE
post-up iptables -t nat -A POSTROUTING -i vmbr0 -p tcp --dport 1080 -j DNAT --to 172.16.0.102:80
post-down iptables -t nat -A PREROUTING -i vmbr0 -p tcp --dport 1080 -j DNAT --to 172.16.0.102:80
