Problem with shares

[kfadrat]

Hello,
I poor in this task, so sorry for stupid questions.

I have configured openvpn on Linksys - OpenWrt, everything worked fine and suddenly ....
I restarted router and start openvpn deamon. On the client side I have openvpn connection

I can ping the server 10.3.0.1, but I have problems with shares in destination network. What could I check to solve the problem. I have the simplest configuration:

server:

dev tun
tun-mtu 1500
# ifconfig local_ip remote_ip
ifconfig 10.3.0.1 10.3.0.2
; port 5000
user nobody
group nobody
comp-lzo

; ping 15
; ping-restart 45
; ping-timer-rem
; persist-tun
; persist-key

verb 3
secret /etc/openvpn/static.key
; eof

and client:

dev tun
tun-mtu 1500
remote ---.---.---.---
# ifconfig local_ip remote_ip
route add 192.168.1.0 mask 255.255.255.0 10.3.0.1

ifconfig 10.3.0.2 10.3.0.1
; port 5000
user nobody
group nobody
comp-lzo

; ping 15
; ping-restart 45
; ping-timer-rem
; persist-tun
; persist-key

verb 3
secret static.key
; eof

I will be gratefull for suggestions and help

I can ping the server 10.3.0.1, but I have problems with shares in destination network.

can you ping a host on the server-side LAN (e.g. 192.168.1.1) ? does the server-side LAN know that all traffic coming from 10.3.0.2 needs to go back to 10.3.0.1 instead of to the default GW? Is routing enabled on the server?

what does 'problems with shares' mean? what happens if you start

Code: Select all

start \\10.3.0.1
start \\192.168.1.x

?

Hi,

I mean that I can ping router on the server-side. I cannot ping computer on ther server-side LAN. When I send command tracert, the packets stoped on router on the server-side LAN. router adress on the server-side lan is 192.168.1.1


from the client side:

C:\Documents and Settings\szczurowscy>tracert 192.168.1.10

Trasa śledzenia do 192.168.1.10 przewyższa maksymalną liczbę przeskoków 30

1 30 ms 49 ms 36 ms 10.3.0.1

On the server-side lan, the client's has the default router to 192.168.1.1 and therefore, all the answers for VPN clients are send to the default router, not to the OpenVPN server. So, in order for routing to work you have to add on every host of server-side lan the route:

Code: Select all

route add 10.3.0.0 mask 255.255.255.0 gw <OpenVPN server lan IP>

[kfadrat]

On the client side I add route liike this:
route add 192.168.1.0 mask 255.255.255.0 10.3.0.1
and it doesn't work.

[Mimiko]

Please read my previous post carefully.

[kfadrat]

hi,

I added route

route add 10.3.0.0 mask 255.255.255.0 192.168.1.1

but it won't help.


Maybe earlierI wrote something wrong.
router: linksys with openWRT
local address of router: 192.168.1.1
address of file serwer is 192.168.1.10

[Mimiko]

It's very bad that you don't read the words carefully and don't whant to understan.
What is the ips of the OpenVPN server?

[kfadrat]

Like I said in the first post sorry for stupid questions. I am really pure in this case.

Ip of my openvpn server is 192.168.1.1. router and openvpn server it is the same machine. Linksys with openwrt

[Mimiko]

What will be the answer if you ping the file server from the router itself? Did you checked the iptables on router? Give a list from "iptables -L -v".

[kfadrat]

HI
I solved the problem. The problem was forward, like you wrote in your last post.

Thanks for help

[Mimiko]

Hm, isn't on routers the forwarding is enabled by default?
