Category: VPS Setup

Set up UFW route rules on Ubuntu—install with

apt install ufw

then edit /etc/ufw/before rules with

nano /etc/ufw/before.rules

adding before *filter:

*nat\n:POSTROUTING ACCEPT [0:0]\n-A POSTROUTING -s 192.168.1.0/24 -o eth0 -j MASQUERADE\nCOMMIT

Enable IP forwarding in /etc/sysctl conf with net ipv4 ip_forward=1 apply with

sysctl -p

and allow SSH with

ufw allow 22

Enable with

ufw enable

On Vultr this routes internal traffic—test with

iptables -t nat -L

expecting \"MASQUERADE\" ensuring MySQL and FTP uptime in multi-NIC setups
