Configuring openvpn server and client

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

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..

so your not natting anything through your vpn interfaces.. Fine since your just all local networks.. But you don't have anything in your remote or local networks You don't normally have to push routes.. Unless your doing something specific odd..

Where are you routing tables from pfsense?

jerryxLinuX

Routing table means? how to get that?

jerryxLinuX

I think you are asking about this

hey success man , i just made an entry in client specific overrides as " iroute 192.168.140.0 255.255.255.0" my client ip . it was success.
Thanks dude.
i have another question how to add multiple client in the server , do i want to continue my post in same thread or want to raise a new thread

johnpoz

no that is not your routing table… under diagnostics routes, it will list out your routing table.

Why should you have to put it in overrides if you would just setup the server and client correctly in the first place? With the local and remote network fields.

divsys

SSL/TLS still needs an iroute via the CSC section for each client.

Much easier in 2.2.5 than it used to be, but that iroute is often a last Gotcha in S2S links.

jerryxLinuX

ok then its necessary right.

divsys

Definitely necessary, in the current pfSense versions, you simply enter into the server screen a comma delimited list of all the subnet "LANs" on all the client OpenVPN's you want to reach.

Then in the Client Specific Overrides section you make an entry for each client and list the LAN subnets that client will use.

It seems a little convoluted for a single S2S connection, but it lets you setup a single server and easily connect many (I have a link that uses 20+) clients each with more than one subnet.

The only hitch is that the client subnets can't overlap - takes a little planning, but welcome to networking ;)

jerryxLinuX

Thank you all for helping me out . see you in next thread soon. going to configure multiple client ,if any error occurs reach you guys , please provide support…. ;D ;D 8) 8) ??? ??? ??? :P :P :P :P

jerryxLinuX

Dude another issue .
I cant export client .
there is no option in remote server what to do?

Screenshot_4.jpg_thumb

divsys

Client export is only for Remote access type OpenVPN servers ("Roadwarriors").

If you need both S2S and Remote access on the same pfSense box, I normally just create a second server instance listening on a different port and using different CA's and Server Certs.

Personally I prefer to keep them separate anyway, easier to track who's logging in remotely.

jerryxLinuX

my requirement is
one vpn server have multiple clients ==> so that users can have access all regions
if i want to work from home i need vpn key
so users from other network should connect this server using openvpn. so client export is necessary.

so what type of vpn server i have to use S2S or remote access open vpn server .

divsys

When you create an OpenVPN server you have to specify the "Server Mode":

Peer to Peer (SSL/TLS) - Used for pfSense to pfSense connections, two routers that are connected 24/7
or
Remote Access (SSL/TLS) - Used for mobile or sporadic devices, laptops, cell phones, users at home computers. They connect when needed.

As I said before, you create the type (or both) that you need for your situation.

Perhaps it would be worthwhile to draw a simple diagram of your envisioned setup so we can all be clear as to what you're trying to accomplish.
