Hello! I have been trying to setup a server for a student radio at my school. This is my first time working with Proxmox. The reason I choose this software was becuse of the flexibility it creates but right now it's been more of a brick wall that I haven't been able to get past. The current issue for me is that none of my vm's can access websites. The outgoing networking work like it should it's just the ingoing for browing websites and update the vm's that isn't working. I have tried with and without the firewall and it doesn't seem to be the source of the issue. I am just kinda lost at this point have been working on this for months and some stuff are now working that wasn't before but I just can't seem to get the networking to work properly. I have been browsing this forum for solutions but have yet to find anyting that has worked. I have attached the current settings for network on my server. Any help would be greatly appreciated.

post-{up,down} commands in /etc/network/interface are always part of an interface stanza. So both these top-level post-{up,down} iptables -t raw .. must be moved to the correct interface for them to work. Afterwards, a ifreload -a should take care of the rest.
