OpenVPN not routing all traffic despite Redirect Gateway checked
-
@netblues I removed 10.55.83.10, and passed no DNS servers to the VPN. Things are now working....Looks like DNS resolver is working for the VPN clients by default, so no list has to be passed.....thank you very much for your help.
-
@wmcneil actually vpn clients are using their internet provider dns. You might have issues accesing internal resources by name.
-
@netblues I could provide the same list of DNS servers that the WAN is using to the VPN. The only drawback is that I am allowing the WAN DHCP DNS servers to override (be placed before) the primary and secondary servers specified in System / General Setup. So I can specify the current numeric IP of those servers for the VPN, but if they change they will not be automatically updated.
-
@wmcneil The correct way is to have openvpn clients use pf sense resolver, for long term stability.
Perhaps specifying the openvpn server ip as dns would work for you. -
@netblues How do I configure pfsense so that the openvpn clients use pfsense resolver?
-
@wmcneil First assign an interface to openvpn.
Then restart openvpn.
dnsresolver should be listening to this new interface too.
So specifying a dns of 10.55.201.1 should work. -
@netblues I created a new interface named OPT2, and assigned it to my OpenVPN server. (settings and status below). I have not assigned any DNS to the OpenVPN yet, because I'm not following why you think 10.55.201.1 will work, as that is an available IP for assignment to a tunnel client?
-
@wmcneil In openvpn the first ip of openvpn tunnel network is always assigned to the server, ie pfsense
-
@netblues Yes, I see now that a client is connected to the VPN the interface assigned to it (OPT2) has been assigned the first tunnel address (10.55.201.1). That said, it does not work to use 10.55.201.1 as the VPN DNS server. If I use the SG-1100 LAN IP (10.55.83.10) as the VPN DNS server, things are working.
-
@wmcneil Ok then, the important thing is to have a pf working dns.
Just remember not to block access to dns with rules.
