Openvpn cannot access to lan

sgtr

Hi,
Firstly, can you explain your modem configuration? As above your network subnet values might be same subnet. Other way did you added a rule (firewall>rules>openvpn) access to local network.

Regards,

Hi,

I just opened the same question (cannot access LAN) so I cannot provide the answer to this question…
But: the firewall rule for OpenVPN is created automatically when configuring OpenVPN (with description OpenVPN wizard).

aykiri1

my modem ip 192.168.5.1 subnet is 255.255.255.0
pfsense ip 192.168.5.2 subnet is 255.255.255.0

all pcs connecting to internet without problem.

remote pc is connecting to pfsense with openvpn client and connection is OK taken ip 10.0.1.6
firewall rules automaticly created . also i checked its available
but can't connect to lolac pcs.

heper

please draw a map for us to understand your network topology. your pfsense only has 1 interface - a LAN interface ?

aykiri1

pfsense
lan 192.168.5.2 subnet 255.255.255.0
wan 192.168.5.1 subnet 255.255.255.0

ovpn tunnel setting 10.0.1.0/24
local network setting 192.168.5.0/24

client connecting to pfsense server and access internet OK. web config pfsense is OK. pinging 192.168.5.2 OK
but no ping or other access to 5.2 5.3 5.4 etc..

pfsense
lan 192.168.5.2 subnet 255.255.255.0
wan 192.168.5.1 subnet 255.255.255.0

The way you have written this, it just won't work. It is not possible to have the same subnet on LAN and WAN. So there is some problem with us being able to understand what you mean.
What is connected to the WAN NIC of pfSense?
What is connected to the LAN NIC of pfSense?
Please try and draw a network diagram of what hardware is connected where.

thanks for helping

adsl_router(192.168.5.1-255.255.255.0) –------- pfsense (192.168.5.2-255.255.255.0) <<< 15 LAN PC (192.168.5.XX 255.255.255.0)

remote pc 10.0.6.6

this is what i want.

that 15 pc and pfsense working properly no any problem.
i want to remote pc add to that lan
installed openvpn client to win7 pc. and connected to pfsense. pinging 192.168.5.2 is OK. web access and internet ok too.
only problem is i can't ping or any access to that 15 pc
firewall rules automaticly created. and i tried to push route 10.0.1.0 255.255.255.0 too
but no success

sgtr

If you want to solve this problem. Firstly you must change modem network subnet. Because your modem and pfSense box are same network. Modem and local network shouldn't be same subnet. They must be different subnet. That's not pfSense problem. It is routing protocol rules. And go to modem gui change modem ip address and pfSense Wan ip address and wan gateway address. You will see problem solved.

i changed to settings this values

adsl_router(192.168.6.1-255.255.255.0) –------- pfsense (192.168.7.2-255.255.255.0) <<< 15 LAN PC (192.168.7.XX 255.255.255.0)

remote pc 10.0.1.6

but no success

phil.davis

I have no idea why your clients worked on LAN when you had 192.168.5.* addresses on pfSense WAN and LAN. Maybe you have pfSense in transparent bridge mode?
Anyway, now you have different subnets on LAN and WAN, which is good. Hopefully the LAN clients in 192.168.7.* are working fine and can get to the internet.
In your OpenVPN server, put "192.168.7.0/24" in "Local Network/s". Then the OpenVPN client should be given a route to 192.168.7.0/24
Make sure your OpenVPN tab has a rule that passes traffic to destination 192.168.7.0/24 (or pass destination all).

hi phil

it was my mistake sorry.

wan and lan was not same. it was 5.2 and 6.2 i was mistake from wan gateway and wan.
just. i changed ips but not success again.

heper

the lan pc's on the 192.168.7.x range have pfsense set as their default gateway ?

could you attempt todo the following in windows command prompt:

from VPN: tracert -d 192.168.7.X
from LANPC (when vpn is connected): tracert -d 10.0.6.6
also some diagnostics–>packet captures would be helpfull (try pinging from both ends while it is running)

That is very strange. It is routing from the OpenVPN client across the VPN link to pfSense, but then pfSense is sending it out the WAN 192.168.5.1 to the public internet. I can't think how that could happen, because 192.168.7.5 is on the local LAN of pfSense, so it has to be delivered directly there.
What is in Diagnostics->Routes IPv4 section on pfSense?

hi phil its output.

and i see on ipconfig

any suggest from specialists ?

Hi Everyone,

Firstly @aykiri1

I confused. Because there was one network when you started this topic. And then there are many networks (192.168.4.0/24, 192.168.5.0/24, 192.168.6.0/24, 192.168.7.0/24 and your tunnel networks).

what are your adsl modem ip and your pfSense wan and Lan ip address? You told us that adsl modem ip changed 192.168.6.1 and you pfSense LAn ip address 192.168.7.2

@aykiri1:

hi SGTR

my second lan and second wan interfaces not important becasue i want to access only lan1 (LAN)

ofcourse i made changes when get info from someone then test by test.

openvpn client 10.0.6.6

firewall rule opnvpn any to any and any port pass added
openv vpn client connecing to server get ip 10.0.6.6 web access pfsense OK. internet OK. lan access NOK

pfsense sets the interface ip in the client-config … in your case this is probably 192.168.....
