VPN Connection Error 628 and 721 over Linksys |
|
|
Help With VPN.
Here is the basic setup.
The office setup:
Two client computers running Win XP SP2
One Server running Windows 2003 SP 1(Single NIC)
Internet connection is through a Linksys WRT564G SRX Router
VoIP with Vonage through a Linksys RT31P2 Router
The VPN server sits behind the WRT54G and the basic configuration is as
follows:
On the properties page of the VPN server:
General tab:
Enable this computer as a:
Router
Lan and Demand-dial routing
Remote access server
All are enabled
Security Tab:
Windows Authentication
IP Tab
Enable IP Routing
Allow IP based remote access and demand dial connections
Using Static address pool.
192.168.1.10 to 192.168.1.20
PPP Tab
All defaults
Logging Tab
Log all events enabled
PORT
WAN Miniport (L2TP) 0
WAAN Miniport (PPTP) 5
Rest Defaults
REMOTE ACCESS POLICY
Day-And-Time Restriction set to default
Tunnel-Type matches Generic Route Encapsulation
Point-to-Point Tunneling Protocol
Windows-Groups matches “VPN Server\VPN Group”
EDIT PROFILE
Authentication TAB
MS-CHAP v2
User can change PW
MS-CHAP
User can change PW
IP TAB
Server settings determine IP address assignments
All other Tabs are default
REMOTE ACCESS LOGGING
Authentication request is enabled
VPN Server IP Addressing:
IP 192.168.1.5
SM 255.255.255.0
DG 192.168.1.1
Static DNS Addresses
WRT54G IP Configuration (updated firmware)
IP 192.168.1.1
DG ISP
PPTP Pass-through is enabled
PPTP 1723 Port is forwarded to VPN Server at 1923168.1.5
DHCP is enabled
MTU 1400
RT31P2 (updated firmware)
IP 192.168.15.1
DG 192.168.1.1
Nothing sits behind this. Just the VoIP service
The DSL Line is setup with Vonage.
Remote Clients
Windows XP Sp2
Both access through DSL
One with a Linksys WRT54G Router and the other through a BEFSR41
PPTP enable and 1723 forwarded.
Client Connection Configuration
General TAB
VPN Server IP Address
Dial another Connection first is Disabled
OPTIONS TAB
Defaults
SECURITY TAB
Advance (custom setting)
Data encryption
Require encryption (disconnect if server declines)
Allow these Protocols are:
MS-CHAP
MS-CHAPv2
NETWORKING TAB
Unchecked Use default gateway on remote network
ADVANCE TAB
Tried firewall both Enabled and Disabled
When connecting to VPN Server I get two errors. One client it is Error 721
and on the other Client it is 628
Both the ISP and Vonage say that I can VPN through their connection.
On the VPN server, I get an Event ID Warning Type error 20209-Source Rasman
It is telling me that a connection has been established but the VPN
connection cannot be completed. It suggests that the most probable cause is
that somewhere along the line, GRE is not being permitted.
Please, any help would be most welcomed.

It could be GRE issue. We have seen many case like that. I would upgrade the
firmware on WRT54G first.

Hello Robert,
When I first started to have this problem I suspected it might be a firmware
problem so I contacted Linksys about my concern with the PPTP through with
it's current firmware and they seemed to know right away what the problem
was. They emailed me the current updated which is 1.02.08 and said this would
correct the Passthrough issue. It did not. I've been successful with some of
the older Linksys routers with the VPN but this one is just been a real pain.
The only difference with this setup is it's got the Vonage VoIP with it. But
they say that should not present a problem.
Again thanks for you response.
