3Com OfficeConnect Remote 812 manual set vc vc name, Remote Site

Where <user name> is the VC Remote Site profile name.

add auto_filter vc_blk_netbios vc <user name>

To create a filter to block NetBIOS file and printer sharing over the Remote Site connection, use the following command:

set vc <vc name> ip_source_validation [DISABLE ENABLE]

To enable IP Source Validation in a profile, use the command:

The IP address associated with the local side of the WAN connection can be specified by you, learned from the remote site (if you are using PPP as the Network Service for the connection), or the interface can be Unnumbered.

To specify the local IP address use the command:

￿set vc <vc name> local_ip_address <ip address>

To specify that the local IP address should be learned you must enter 255.255.255.255 for the <ip address> parameter. To specify that the interface is Unnumbered you must enter 0.0.0.0 for the <ip address> parameter.

For a discussion of Unnumbered (and Numbered) interfaces, see “Configuring IP Routing” in the Online User’s Guide.

Optionally, you can specify that the remote site should be used as the default gateway.

IP Routing

6-17

To designate the remote site as the default gateway use the command:

￿	set vc <vc name>
	default_route_option [DISABLE ENABLE]

The default_route_option can only be enabled in one VC profile.

Also, you can configure IP Source Validation for the connection. When IP Source Validation is enabled, the source address of all IP frames received from the remote site will be validated. A packet’s source address is valid if the OCR 812 will route an IP frame destined to the source address on the same VC it came in on.

￿￿This command creates a filter which rejects incoming frames with destination UDP ports 137 and 138, and destination TCP ports 139 and 143. The filter is automatically added to the filter manager and attached as the Remote Site’s profile input filter.

Configuring IP RIP for a IP RIP can be enabled or disabled for each remote site connection.

Remote Site

The OCR 812 supports two versions of RIP, V1 or V2. Additionally, you can configure whether the OCR 812 should advertise local routes, only listen for routes from the remote site, or both.

￿	To configure RIP for a remote site connection:
	set vc <vc name>
	ip_routing [BOTH	LISTEN NONE SEND]
