[SOLVED] Virtual machine without internet access (Mikrotik RouterOS)

[profjvidal]

Good afternoon.

If someone can help, have the following configuration:
- The platform is a debian 9 VPS.
- I installed the proxmox and a virtual machine with Mikrotik RouterOS, this is already configured, but has no internet.

Check out my configuration:

No debian 9(proxmox):

auto lo
iface lo inet loopback


auto ens3
iface ens3 inet static
address 185.xx.xx.100
network 185.xx.xx.0
netmask 255.255.255.192
gateway 185.xx.xx.4


post-up echo 1 > /proc/sys/net/ipv4/ip_forward
post-up echo 1 > /proc/sys/net/ipv4/conf/ens3/proxy_arp


auto vmbr0
iface vmbr0 inet static
address 10.10.10.1
netmask 255.255.255.0
bridge_ports none
bridge_stp off
bridge_fd 0

source /etc/network/interfaces.d/*.cfg

No mikrotik:
In mikrotik is already configured the route, dns and nat. Ping for ip 10.10.10.1 and 185.xx.xx.100 are working but for external, type 8.8.8.8 does not work.

Good afternoon. Problem solved.

root@proxmox:~# nano /etc/init.d/proxmox-routing
#!/bin/sh
case "$1" in
start) echo "proxmox-routing started"

/sbin/iptables -t nat -A POSTROUTING -s 10.0.0.0/8 -o ens3 -j SNAT --to 185.xx.xx.100

/sbin/iptables -A FORWARD -s 10.0.0.0/8 -j ACCEPT
/sbin/iptables -A FORWARD -d 10.0.0.0/8 -j ACCEPT

exit 2
;;

esac
exit 0

root@proxmox:~# chmod 755 /etc/init.d/proxmox-routing

Hi,

Can you please make some throughput tests with the Mikrotik RouterOS? Is it using a lot of resources? What is your hardware configuration? Did you also test pfSense for comparation?

Thank you,
Rares
