I have a bare-metal Proxmox server running with two public IPs. The initial configuration has already been done, and the containers are running with a NAT and a private network.
I currently have 2 public IPs:
190.140.147.92 (This is the available one)
This one has a comment in the interface that says #route 190.140.147.64/26 via 190.140.147.65

190.140.147.111 (this is the Proxmox one)

Apparently the person who did the initial setup did a nat masquerade with the available IP, and I need to use either one. I tried to do a bridge with each of the 2 ip's and it didn't work, it shows this:

icmp_seq=1 Destination Host Unreachable

This is the current configuration.

Code:
source /etc/network/interfaces.d/*

auto lo
iface lo inet loopback

iface lo inet6 loopback

auto enp195s0
iface enp195s0 inet static
address 190.140.147.92/26
gateway 190.140.147.65
up route add -net 190.140.147.64 netmask 255.255.255.192 gw 190.140.147.65 dev enp195s0
# route 190.140.147.64/26 via 190.140.147.65

iface enp195s0 inet6 static
address 9a01:4f8:261:1966::2/64
gateway fe80::1

auto enxfe9a2a6a0631
iface enxfe9a2a6a0631 inet static
address 190.140.147.111/26

auto vmbr0
iface vmbr0 inet static
address 192.168.0.1/24
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 '192.168.0.0/24' -o enp195s0 -j MASQUERADE
post-down iptables -t nat -D POSTROUTING -s '192.168.0.0/24' -o enp195s0 -j MASQUERADE
