OpenVpn Firewall Rule

assatum · January 22, 2020, 9:02am

Hello community,

I tried to set up OpenVPN on an OpenVPN router, and something goes always wrong. I followed this description: https://openwrt.org/docs/guide-user/services/vpn/openvpn/basic
My goal is to reach the computers on the LAN, and I would like to use internet trough VPN as well. I can connect to the router trough VPN, but if the connection is established, nothing is reachable. I can't ping neither the routers internal port, nor external IP addresses. If I connect via lan cable (so I am in internal network) everything works smoothly.
So could anybody help me to solve this problem? Probably firewall rules are missing, but I couldn't configure it. I tried lot of descriptions, but I didn't get solution.

Thanks and regards,
assatum

I don't see any problem at the server side.

What is the client? PC or smartphone? What OS does it run? Any firewall/antivirus running? Post also the client config and if possible the equivalent of route command when connected.

assatum · January 22, 2020, 12:12pm

I connect from Windows Laptop.

192.168.8.2 is the IP which belongs to VPN

Fix the post above and use preformatted text for the console output (the </> button)
Install tcpdump on the OpenWrt router:
opkg update ; opkg install tcpudump
Then let a tcpdump capture packets from the vpn user:
tcpdump -i any -vn host 192.168.8.2
Make sure the windows pc has the IP 192.168.8.2 and start a ping or traceroute from the windows pc to some host in the LAN, can be 192.168.82.254 .
Post here the output.

psherman · January 22, 2020, 6:11pm

I think that you want to change this to your LAN (192.168.82.254)
And I think you also need to add a push directive to add the route to 192.168.82.0/24

You'll want these lines in your OpenVPN file:

list push 'route 192.168.82.0 255.255.255.0'
list push 'dhcp-option DNS 192.168.82.254'

If that doesn't work, can I trouble you to post the contents of the /etc/config/network, /etc/config/firewall, /etc/config/openvpn, and /etc/openvpn/server.conf files directly (use cat <file> and then copy/paste into a preformatted text block to preserve the formatting and such). I find it much easier to read than UCI output (personal preference).

One of my colleague found the solution, it was:
"redirect-gateway autolocal" on the client side

Since that, the LAN/WAN access works with VPN.
Many thanks to everybody for the effort

I believe this is caused because you were trying to access the VPN server from the same subnet. I you connected from the internet it would not occur.
https://community.openvpn.net/openvpn/wiki/Openvpn23ManPage

Automatically execute routing commands to cause all outgoing IP traffic to be redirected over the VPN. This is a client-side option.

This option performs three steps:

(1) Create a static route for the --remote address which forwards to the pre-existing default gateway. This is done so that (3) will not create a routing loop.

(2) Delete the default gateway route.

(3) Set the new default gateway to be the VPN endpoint address (derived either from --route-gateway or the second parameter to --ifconfig when --dev tun is specified).

When the tunnel is torn down, all of the above steps are reversed so that the original default route is restored.

Option flags:

local -- Add the local flag if both OpenVPN servers are directly connected via a common subnet, such as with wireless. The local flag will cause step 1 above to be omitted.

autolocal -- Try to automatically determine whether to enable local flag above.
