What VPN feature allows traffic to exit the security appliance through the same interface it entered?This feature is useful for VPN traffic that enters an interface, but is then routed out of that same interface. For example, if you have a hub-and-spoke VPN network where the security appliance is the hub and the remote VPN networks are spokes, in order for one spoke to communicate with another spoke traffic must go to the security appliance and then out again to the other spoke.Enter the same-security-traffic command in order to allow traffic to enter and exit the same interface. ciscoasa(config)#same-security-traffic permit intra-interfaceReference: http://www.cisco.com/c/en/us/support/docs/security/asa-5500-x-series-next-generation-firewalls/100918-asa-sslvpn-00.html
