Outbound access describes connections from a higher security level interface to a lower security level interface. This includes connections from inside to outside, inside to Demilitarized Zones (DMZs), and DMZs to outside. This can also include connections from one DMZ to another, as long as the connection source interface has a higher security level than the destination. Review the "security-level" configuration on the PIX interfaces in order to confirm this. This example shows the security level and interface name configuration: pix(config)#interface ethernet 0 pix(config-if)#security-level 0 pix(config-if)#nameif outside pix(config-if)#exit PIX 7.0 introduces the nat-control command. You can use the nat-control command in configuration mode in order to specify if NAT is required for outside communications. With NAT control enabled, configuration of NAT rules is required in order to allow outbound traffic, as is the case with previous versions of PIX software. If NAT control is disabled (no nat-control), inside hosts can communicate with outside networks without the configuration of a NAT rule. However, if you have inside hosts that do not have public addresses, you still need to configure NAT for those hosts. ... View more

If you are trying to set up a SIP trunk from your CallManager to Broadvoice, you may run into an issue with Broadvoice not allowing you're router (acting as IOS SIP gateway) to maintain a Registered status. This is due to having the IP Phones on your network all sending SIP Register requests to Broadvoice. So try to input the "no-reg primary" on each ephone and ephone-dn in your config. ... View more

In ESX Virtual Switch Tagging (VST Mode) mode, you provision one port group on a virtual switch for each VLAN, and then attach the virtual machine's virtual adapter to the port group instead of the virtual switch directly. The virtual switch port group tags all outbound frames and removes tags for all inbound frames. It also ensures that frames on one VLAN do not leak into a different VLAN. Native VLAN ID on ESX VST Mode is not supported. Do not assign a VLAN to a port group that is same as the native VLAN ID of the physical switch. Native VLAN packets are not tagged with VLAN ID on the out going traffic toward ESX host. Therefore, if ESX is set VST mode, it drops the packets that are lacking a VLAN tag. ... View more

You can configure H.323 gateways either with gatekeeper control or locally as gateways. Sometimes an anonymous H.323 device, a device that is not known to Cisco Unified Communications Manager, tries to initiate (send or receive) calls with Cisco Unified Communications Manager. This anonymous device could be a Cisco IOS product (such as a gateway) or any third-party H.323 device. ... View more
