v Note: Subinterfaces are only allowed on WAN ports configured for Frame
Relay operation. They are not allowed on WAN ports configured for PPP.
Frame Relay Glacis must be statically mapped when subinterfaces are in use,
because IARP can only resolve a physical port, not a logical subinterface on
that port.
IP Connection Dialog Box
IP Connection Dialog Box
The IP Connection Dialog Box controls the IP settings for the IPSec-only port
on an IntraPort VPN Access Router with two or more Ethernet interfaces.
This port will only handle IPSec traffic (i.e., authenticated and/or encrypted
packets).
To access this dialog box, select Ethernet/TCP/IP Routing from the Device
View.
> IP On/IP Off
This set of radio buttons controls how IP packets are handled for this inter-
face.
• If set to IP On, then IPSec packets received on this interface are routed
to the correct interface on the router.
• If set to IP Off, then any IP packets received on this interface are
discarded.
