I am trying to allow my appVM to communicate with my samba server on my local network. The problem is that I am forcing this appVM to go through a proxyVM which doesn't allow traffic to pass through unless its going via the VPN (openvpn).
So I am trying to add iptables rules to allow this, but I can't seem to get it to work, and am wondering what I am missing. The following rule is the one I add to the proxyVPN (which should be the only VM I have to edit, right?)
iptables -I FORWARD 1 -d <samba-server-ip> -p tcp -m multiport --dports 137:139,445 -j ACCEPT
After attempting to connect to the server I can see that the target rule gets hit a couple of times (6 to be exact), but I am still getting
"mount error(115): Operation in progress"
error message from the appVM when trying to mount a cifs-share. I also cannot see any DROP rules being hit, which leads me to believe that maybe I will have to edit the iptables rules in the firewallVM or the netVM or even the appVM, but I can't think of why that should be.
Any help is very much appreciated!
