Unable to reach LAN IP after connecting to openvpn

[ayanbanerjee]

@comet424 As per the video I have changed the VPN ip pool 172.16.12.x but same thing ... still I am unable to ping any of the lan ip which are belongs on 192.168.1.x series.

Please post up your openvpn config, your client config and what IP is your client on when you connect..

Not going to watch a 15 min video for something that takes 30 seconds to setup. Clickity Clickity through the wizard, export the client config = done..

@johnpoz Hi,

Please find below the VPN config details

dev tun
persist-tun
persist-key
cipher AES-256-CBC
ncp-disable
auth SHA1
tls-client
client
resolv-retry infinite
remote 182.71.195.102 1194 udp
verify-x509-name "IndepayVPNCertificate" name
auth-user-pass
pkcs12 pfSense-UDP4-1194-ayanbanerjee.p12
tls-auth pfSense-UDP4-1194-ayanbanerjee-tls.key 1
remote-cert-tls server

172.16.12.2 is getting when my vpn got connected.

[johnpoz]

why are you putting that in custom options? Remove that.

Is your client getting the option to force all traffic out tunnel. What is the clients IP, not its vpn tunnel IP it gets. As already mentioned if your remove client is on the same network as your remote network its not going to work.

Lets see your clients route after you connect and the status of when your client connects... example

see here is my routes being added to the client per my above post

but I loose internet and I cant ping…

Can't ping what?? Is what your trying to ping set to allow you to ping from 192.168.100/24 - for example windows out of the box firewall will not answer ping unless your on the same network..

You have to adjust the host firewall. For you to get internet access via this vpn connection, did you set your outbound nat for your tunnel network.. Should of done that for you, but if you had changed to say manual mode on your outbound nat than it wouldn't..

When you connect to your vpn, can you ping your lan IP of pfsense?

[ayanbanerjee]

@johnpoz Hi, I have already removed the custom option.

My client IP is 192.168.5.100

[johnpoz]

so do a traceroute.. What do you get from that?

example here is traceroute to IP on my home lan network

C:\Windows\System32>tracert -d 192.168.9.100

Tracing route to 192.168.9.100 over a maximum of 30 hops

1 101 ms 108 ms 103 ms 10.0.8.1
2 106 ms 101 ms 109 ms 192.168.9.100

Trace complete.

C:\Windows\System32>

Its long because my proxy is all the way in TX, while I am at work in Chicago, so from chicago to hou, back to chicago, etc. So yeah some added latency.

Ping and traceroute to the pfsense lan IP.. For example my pfsense IP on my lan is 192.168.9.253.. You trying to talk to devices on your lan might have host firewalls blocking your remote tunnel IP.

[ayanbanerjee]

@johnpoz Hi, here is the story, I am able to reach the pfsense lan ip which is 192.168.1.2 but to ping any f the ip which are belongs to 192.168.1.x series.

[johnpoz]

Well then your going down the tunnel and as already stated points to host firewall, or the host your trying to ping using a different gateway other than pfsense.

You not being able to get to say public iP 8.8.8.8 down the tunnel would point to outbound nat not configured for your tunnel network on pfsense.

[ayanbanerjee]

@johnpoz Hi, we are using only one GW and that is PfSense local ip 192.168.1.2 and also able to ping 8.8.8.8 or 4.4.2.2 when I am in VPN.
I am really clueless now :(

here is my outbound nat I set

as for the pinging what I ment was on my cell I have a Ping program when I'm not on my vpn I can ping say 192.168.0.15 which is my Freenas IP as soon as I connect to VPN I get the 192.168.100.2 for my cell and I loose all internet.. I can no longer ping 192.168.0.15(freenas) I cant ping 192.168.0.1 the router or 192.168.100.1 which be the router I in virtual lan setting and this happens when I connect open vpn using my home internet or at the coffee shop

I'm sure its something simple like a check box I missed that's causing all this right? for the traceroute id have to be at the coffee shop with the openvpn to get the results you want correct?

[comet424]

the only ip address I can ping while on vpn is 192.168.100.2 which is the cells ip address for the vpn..

so I confused I thought was so simple like the video showed boom boom boom done now your perfectly connected... I had to missed a step some how probably some check box I missed

here is the Rules pics for the firewall for the openvpn

That is not a network that is a host!!! network would be 192.168.1.0/24
