Hello server enthusiasts,
I have a VPN (pptpd running on Ubuntu 10.04) that I am trying to connect to with a client (Win7).
I can successfully connect to the VPN.
Once connected to the VPN, I can ping both interfaces on the server (188.8.131.52 which is a public IP facing the internet, and the address used to connect to the VPN server (eth0), and 192.168.0.1 (ppp0)).
I cannot ping any other addresses from the Win7 client. IP forwarding is enabled server side.
I am having trouble adding a route via the windows route command.
Server: eth0 – 184.108.40.206 (facing internet),
ppp0 – 192.168.0.1
Client: VMware Win7
ppp – 192.168.1.1
ipconfigon Win7 client:
Default Gateway: 0.0.0.0 IP: 192.168.1.1 Subnet: 255.255.255.255
I have tried
route ADD 192.168.0.1 255.255.255.255 192.168.0.1 route ADD 220.127.116.11 255.255.255.255 192.168.0.1 route ADD 192.168.0.1 255.255.255.255 192.168.1.1 METRIC 266
All fail, telling me that
Incorrect argument 192.168.1.1
Incorrect argument 192.168.0.1
There are also 2 metrics corresponding to these IP’s in the tables that display as a result of
route printWhich must be used?
I would appreciate if someone could shed light on how to add this particular route.
When adding routes, must I always specify a metric and/or interface? Is there anything unique about adding VPN based routes?
Thank you for reading.
Default Gateway: 0.0.0.0
Your Default Gateway is wrong, try fixing that first.
0.0.0.0 is the any address, and not a valid IP for a host. Basically, your network is configured to shove traffic out to any address, rather than the address it should send its traffic to.
This is also wrong. That’s the subnet mask for a single host, which is presumably not what you want.
Finally, your syntax for the
route add command is all kinds of wrong.
You should be using:
route add [destination IP] MASK [destination subnet mask] [IP of gateway used to reach destination IP], but this requires knowing what those terms mean, as well as having some idea about what networks or hosts you need to connect with a route, and it doesn’t sound like you do, to be quite honest. As I said in the comments, you seem like you’ll need to contact your helpdesk or network administrator to get you through this.
Manipulates network routing tables. ROUTE [-f] [-p] [-4|-6] command [destination] [MASK netmask] [gateway] [METRIC metric] [IF interface] -f Clears the routing tables of all gateway entries. If this is used in conjunction with one of the commands, the tables are cleared prior to running the command. -p When used with the ADD command, makes a route persistent across boots of the system. By default, routes are not preserved when the system is restarted. Ignored for all other commands, which always affect the appropriate persistent routes. This option is not supported in Windows 95. -4 Force using IPv4. -6 Force using IPv6. command One of these: PRINT Prints a route ADD Adds a route DELETE Deletes a route CHANGE Modifies an existing route destination Specifies the host. MASK Specifies that the next parameter is the 'netmask' value. netmask Specifies a subnet mask value for this route entry. If not specified, it defaults to 255.255.255.255. gateway Specifies gateway. interface the interface number for the specified route. METRIC specifies the metric, ie. cost for the destination. All symbolic names used for destination are looked up in the network database file NETWORKS. The symbolic names for gateway are looked up in the host name database file HOSTS. If the command is PRINT or DELETE. Destination or gateway can be a wildcard, (wildcard is specified as a star '*'), or the gateway argument may be omitted. If Dest contains a * or ?, it is treated as a shell pattern, and only matching destination routes are printed. The '*' matches any string, and '?' matches any one char. Examples: 157.*.1, 157.*, 127.*, *224*. Pattern match is only allowed in PRINT command. Diagnostic Notes: Invalid MASK generates an error, that is when (DEST & MASK) != DEST. Example> route ADD 18.104.22.168 MASK 22.214.171.124 126.96.36.199 IF 1 The route addition failed: The specified mask parameter is invalid. (Destination & Mask) != Destination.
