I have a Debian Server setup with OpenVPN and apache running great. Currently the apache services are accessible to everyone. I want to restrict them to only be accessible to clients connected via the VPN.

Here is my incorrect UFW settings

Code: Select all

Status: active
Logging: off
Default: deny (incoming), allow (outgoing)
New profiles: skip

443/tcp                    ALLOW OUT   10.1.0.0/16
80/tcp                     ALLOW OUT   Anywhere on tun0
443/tcp                    ALLOW OUT   Anywhere on tun0
80/tcp                     ALLOW OUT   Anywhere (v6) on tun0
443/tcp                    ALLOW OUT   Anywhere (v6) on tun0

Anyone have any idea how to accomplish what I'm trying to do? I feel like it should be pretty easy, but I have wasted a lot of time on this so far.

Personally, I would use iptables and set rules to block packets to your services except for the VPN packets.

It is relatively easy to do ..

Hello,

I'M trying to do the same config!

Here is my incorrect setup to close apache access:

Code: Select all

22                         ALLOW       Anywhere 
1194/udp                   ALLOW       Anywhere
80/tcp                     ALLOW       10.8.0.0/24 »» this rule should be fine in order to allow apache access for openvpn clients but ufw block the traffic.

Also I did this steps:

in /etc/default/ufw conf:

Code: Select all

DEFAULT_FORWARD_POLICY="ACCEPT"

in /etc/ufw/before.rules conf:

Code: Select all

# START OPENVPN RULES
# NAT table rules
*nat
:POSTROUTING ACCEPT [0:0] 
# Allow traffic from OpenVPN client to eth0
-A POSTROUTING -s 10.8.0.0/24 -o eth0 -j MASQUERADE
COMMIT
# END OPENVPN RULES

Syslog:

Any idea please?
I need just close apache access for public, only ovpn connected clients should be able to access.

..Just a thought, but I believe you can achieve this with a few lines in your .htaccess file:

Order Deny,Allow
Deny from all
Allow from 192.168.1.1/24 ##or whatever your subnet
