Configuring openvpn server and client

[divsys]

Well those log files look like the client isn't connecting properly with the server.

I would suggest you simplify your setup down to one server and one client at first.  If you've already setup a number of other clients trying to connect to your server it maybe worthwhile to change the port# that the server listens on and update only the one test client with that new port.  That way the previous setups won't be doing conflicting connection attempts, but can be brought online fairly simply at a later date.

So for the first connection:

What's?:

Server LAN address
Client LAN Address
OpenVPN Tunnel address

Can you post the Server config screen?
Can you post the Client config screen?

[johnpoz]

this is going to cause it to fail every time

local='auth SHA256', remote='auth SHA1'

You have to be using the same..  I would post up your server and client configs..

one doubt –---------------> in the 3rd line why its showing "tun-ipv6" im using ip4 only .

anything else????

[johnpoz]

So in your client you have

auth SHA256

Where is auth statement in your server config??
At a loss to how that could go missing???  Unless your manually messing with the .conf file?

[jerryxLinuX]

See in my server GUI
there is no option ,so  do i want to manually add in server.conf file?
im using version 2.1.4

[doktornotor]

@jerryxLinuX:

No. You want to upgrade your pfSense.

[jerryxLinuX]

ok i try in other network were pfsense is updated. and let you know.

[jerryxLinuX]

While trying from another two network its working fine , in vpn status i got status " up and bytes sent and received are changing only in bytes:
but while trying to ping from one network to other it fails.

[jerryxLinuX]

sorry for the wrong update , client can access the server but server is not responding to client .
what might be the issue .
while trying ping from client its success ,
while trying ping from server to client it fails

[johnpoz]

firewall on client is quite often blocking…

[jerryxLinuX]

Still same problem , server cant able to access client
checked firewall i have made rules same as server on client.
any configuration for firewall rules do you have

[jerryxLinuX]

Firewall/Rules
Tab OpenVPN
Create rule: pass, any, any, any

i gave all but still now no luck

[doktornotor]

Which part of "firewall on client" was confusing? Most importantly - there are firewall logs, use them!!!

[jerryxLinuX]

how to check firewall log?
status–>systemlogs-->firewall tab. is it so : i have found oly tcp are blocked in my client Ip varies not the server IP is blocked in there.

in server config
what to mention in advanced option
push "route server.o subnet" ; route client.o subnet;
is this the correct way ? why we are doing this?
in my case
eg. push "route"192.168.114.0 255.255.255.0";route 192.168.140.0 255.255.255.0

[johnpoz]

Dude.. The CLIENT firewall… Why would that be in logs on pfsense?

What OS is your client?

[jerryxLinuX]

the client firewall is also pfsense . i am trying to communicate b/w two pfsense.
or i mistook your question

[johnpoz]

So where did you state that?  What IP are you trying to ping?  An IP on the network in your site to site connection?  Or the pfsense client vpn IP, or its lan or its wan??  What?

Did you create a peer to peer or a remote access on the server pfsense?  What networks do you have at each site??

edit:  Dude while I don't normally mind PMs with questions, etc..  Post your stuff in this thread… And what networks are on each side and what is the tunnel network..  Who exactly are you trying to ping..  These are basic questions that we need to know if you want any sort of help..

so my server ip is : 192.168.114.254
my client ip is : 192.168.140.254

i can ping from client(140.254) to server(114.254) , but not from server(114.254) to client(140.254)

any other info needed , sorry for giving less details

[johnpoz]

please just post up a gui shot of your client config and server config..  Your not editing the .conf manually are you?

What do you have in your outbound nat on the client?  On the server?  What is the routing table on pfsense of the client look like and on the server side..  On the client you should be putting in what networks are remote..

[jerryxLinuX]

herewith i have attached all the config screenshots
