LXC guest not exposing ports when using static IP

[masobrinho]

Hi!
I'm fairly new with Proxmox - first installation last monday - and I'm having an strange issue.

LXC containers are working fine when its Network Device is set up to use DHCP.
If I change the setup to have an Static IP, container can still connect to other local ips/the internet.
External hosts (including the Promox host machine) can still ping the container but every port seems to be firewalled.

I'm probably doing something dumb, but I've checked everything many times to no avail.

Any ideas? Thanks in advance!

HA, found it. My netmask was wrong.

Thanks!
