Thanks for the quick response. If the IP lease duration time is set to 60 minutes, a renewal request is sent after 30 minutes. The assignment takes place once the user connects and authenticates.

A remote user can connect to the VPN using the Secureclient, get authenticated and successfully connected and assigned an IP through the IP Pool I have setup, also they get the dns servers I have them pointed to, but they can't access the internal LAN to get to our Exchange server and file servers, nor does their internet access work after connected.

Hub mode is also enabled. The Secureclient log shows deny and gives the error "Packet is from physical IP address but office mode is enabled".

I have tried this from internally and remotely and I get the same issue. My traffic is blocked to any internal LAN so even if I try to ping a local server I get "can't find" etc.

Cause SecureClient with Office Mode in Hub Mode adds a default route to the routing table when a connection is established. The original default route, made by the operating system, will remain in the routing table, but will have its metric increased.

Windows has a mechanism enabled by default, called Dead Gateway Detection. This mechanism monitors multiple default routes to see if connections are failing through them. In the event of failure, Dead Gateway Detection changes the default route from the Office Mode gateway to the operating-system gateway.

SecureClient will drop outbound packets that are not received through the Office Mode interface when Office Mode is enabled. Solution In most cases, the solution for this issue is to use Office Mode with a range of IP addresses that do not exist on the internal network or WAN.

When connecting from a hotel that has an IP address range that overlaps the internal network, the firewall sees the connection attempt as an internal connection, and it will fail to authenticate. Always back up the registry before making any modification. If you DO circumvent it, and they catch you, you'll probably be in big trouble.

I suppose you're right - thanks: For windows, it would require the following command run on the command line as administrator: You can repeat this command for each server you need to access over the VPN. This may work definitely worth trying at least: Thanks, this looks interesting.

There seems to be an argument missing though, docs say it should be: Now, I know the destination and interface , and for the mask I understand I need Any ideas where I get the gateway from? Thanks, I'll check it out. Any way to figure it out from home though? I'm afraid not that I know of, unless there's a second entry in the routing table route print for 0. The client log shows Quote: Sign up or log in Sign up using Google.

It is also useful in early integration stages of Office Mode, allowing you time to "pilot" this feature on a specific group of users, while the rest of the users continue to work in the traditional way. When you connect to the organization, an IKE negotiation is initiated automatically to the Security Gateway.

During config mode, the client requests an IP from the Security Gateway. The routing of packets to the corporate LAN is modified to go through this adapter. Before exiting through the real adapter, the packets will be IPSec encapsulated using the external IP address assigned to the real adapter as the source address. This will allow packets on the LAN being sent to the client to be routed back through the Security Gateway.

The following steps illustrate the process taking place when a remote user connected through Office Mode wishes to exchange some information with resources inside the organization:. The internal IP addresses assigned by the Security Gateway to the remote user can be allocated using one of the following methods:.

The System Administrator designates a range of IP addresses to be utilized for remote client machines. Each client requesting to connect in Office Mode is provided with a unique IP address from the pool.

IP addresses from the IP pool may be reserved and assigned to remote users based on their source IP address. When a remote host connects to the Security Gateway, its IP address is compared to a predefined range of source IP addresses.

If the IP address is found to be in that range, then it is assigned an Office Mode IP address from a range dedicated for that purpose. The IP addresses from this reserved pool can be configured to offer a separate set of access permissions given to these remote users. The attributes are pre-configured on the client side operating system, and can be used by different DHCP servers in the process of distributing IP addresses. When a remote user connects to a Security Gateway, the username and password are passed on to the RADIUS server, which checks that the information is correct, and authenticates the user.

A flat network is one in which all stations can reach each other without going through a bridge or a router. One segment of a network is a "flat network".

A static route is a route that is manually assigned by the system administrator to a router and needs to be manually updated to reflect changes in the network. If the LAN is non-flat stations reach each other via routers and bridges then the OM address of the remote client must be statically assigned to the routers so that packets on the LAN, destined for the remote client, are correctly routed to the Security Gateway. When a remote user's machine is assigned an Office mode IP address, that machine can use it for a certain amount of time.

This time period is called the "IP address lease duration. If the IP lease duration time is set to 60 minutes, a renewal request is sent after 30 minutes. If a renewal is given, the client will request a renewal again after 30 minutes. If the renewal fails, the client attempts again after half of the remaining time, for example, 15 minutes, then 7. If no renewal is given and the 60 minutes of the lease duration times out, the tunnel link terminates. To renew the connection the remote user must reconnect to the Security Gateway.

Upon reconnection, an IKE renegotiation is initiated and a new tunnel created. The default is 15 minutes. When a user disconnects and reconnects to the Security Gateway within a short period of time, it is likely that the user will get the same IP address as before. To facilitate access of a remote user to resources on the internal network, the administrator can specify WINS and DNS servers for the remote user.

This information is sent to the remote user during IKE config mode along with the IP address allocation information, and is used by the remote user's operating system for name-to-IP resolution when the user is trying to access the organization's internal resources. With Anti Spoofing, a network administrator configures which IP addresses are expected on each interface of the Security Gateway.

Anti-spoofing ensures IP addresses are only received or transmitted in the context of their respective Security Gateway interfaces. Office Mode poses a problem to the anti-spoofing feature, since a client machine can connect and authenticate through several interfaces, e. Typically, routing is performed before encryption in VPN. In some complex scenarios of Office Mode, where the Security Gateway may have several external interfaces, this might cause a problem.
