Fixing IPTABLES firewall rules Ubuntu 20.04, KVM, Bridge Network
Budget: $10 – $30 USD
I need help fixing some IPTABLES rules on Ubuntu Server 20.04 LTS. This server is for virtualization using KVM and Bridge Network. 2 Nics, need to forward ports to specific internal IPs.
30 min to discuss best practices on both IPTABLES and KVM (HOST on raid1), including HUGE PAGES and LVM vs QCOW2. Remove UFW and use only IPTABLES. Applying rules using scripts.
iptables-save always shows rules that I already remove, even using iptables -F and iptables -X, iptables-save keeps showing rules. ufw is disabled but still needs to know where are those rules came from.
