SNIP
Hi All,
I'm having a problem with cross subnet browsing and name resolution
across
an openvpn tunnel. i've found quite a few people who've had the same
on
mail lists but none of their fixes have worked. The spec of the setups
at
both ends of the tunnel are as follows:
"remote announce = 192.168.2.255/NEWDOM
192.168.1.255/NEWDOM
remote browse sync = 192.168.1.255 192.168.2.255"
This looks odd to me.
remote announce = <wins server ip>/<DOMNAME>
remote browse sync = <wins server ip>
NEEDED in both smb.conf
wins server = <wins server ip>
Can't remember default for this setting sooooo
enhanced browsing = Yes
in both smb.conf
DHCP should point clients to headoffice for WINS. WINS proxy is not
useful.
OS - CentOS 5.5
Samba Version 3.5.4
OpenVPN Version 2.0.9-1
Each server is configured in gateway mode with two NICS, one to the
lan
and the other to a modem/router. The first machine, HEADOFFICE, has
an
internal IP address of
192.168.0.1 and an external of 192.168.10.4. The second machine,
REMOTE1,
has an internal address of 192.168.1.254 and an external of
192.168.20.4.
On openVPN, I have configured client to client and routes and iroutes
to
allow machines on each network to ping machines at the other end as
well
as the server IP's.
So far so good and I can ping any machine on either subnet from
anywhere
and get a reply. The servers are configured as Samba servers with the
HEADOFFICE machine working as a PDC, DMC and WINS server and the
REMOTE1
machine configured as a BDC and WINS proxy. In order to maintain
logon
facilities in the event of broadband failure,
I have replicated the LDAP server from HEADOFFICE to REMOTE1 and
updates
and password changes propogate successfully from one site to the
other.
If I try to access HEADOFFICE from REMOTE1 and REMOTE1's subnet it
works
perfectly but trying to access REMOTE1 from HEADOFFICE and its subnet
fails on name resolution while
entering \\192.168.1.254\ brings up Windows Explorer and a list of
shares.
I've included the remote browse entries in smb.conf on the PDC and
have
WINS Proxying set up on the BDC but I can't get it to push REMOTE1's
IP
back to the WINS server.
Port scanning the internal IP of each machine from the oher end of the
tunnel returns a full set of open ports for the services I'm using but
no
IP.
If anyone can spot what I'm doing wrong I'd be grateful.
Thanks.
