Configuring Management Access Over a VPN Tunnel

The following example shows how to allow the host at 10.1.1.15 to use only ping to the inside interface,
enter the following command:

hostname(config)# icmp permit host 10.1.1.15 inside

The following example shows how to deny all ping requests and permit all packet-too-big messages (to
support path MTU discovery) at the outside interface:

hostname(config)# ipv6 icmp deny any echo-reply outside

hostname(config)# ipv6 icmp permit any packet-too-big outside

The following example shows how to permit host 2000:0:0:4::2 or hosts on prefix 2001::/64 to ping the
outside interface:

hostname(config)# ipv6 icmp permit host 2000:0:0:4::2 echo-reply outside

hostname(config)# ipv6 icmp permit 2001::/64 echo-reply outside

hostname(config)# ipv6 icmp permit any packet-too-big outside

Configuring Management Access Over a VPN Tunnel

If your VPN tunnel terminates on one interface, but you want to manage the ASA by accessing a different
interface, you can identify that interface as a management-access interface. For example, if you enter the
ASA from the outside interface, this feature lets you connect to the inside interface using ASDM, SSH,
Telnet, or SNMP; or you can ping the inside interface when entering from the outside interface.
Management access is available via the following VPN tunnel types: IPsec clients, IPsec site-to-site, and
the AnyConnect SSL VPN client.
