Hello I am a student and DIY guy. I am in the middle of configuring Cisco ASA (remotely to my school as a project), I have to configure it according to BSD configuration but I have never seen that in real life. Google is not helping me with that.
I have these interfaces:
[CODE]gif0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> metric 0 mtu 1280
tunnel inet aaa.aaaa.aaa.aaa --> bbb.bbb.bbb.bbb
inet ccc.ccc.ccc.ccc --> ddd.ddd.ddd.ddd netmask 0xffffff00
options=1<ACCEPT_REV_ETHIP_VER>
tun0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> metric 0 mtu 1500
inet x.x.x.x --> y.y.y.y netmask 0xffffffff
Opened by PID 14987
[/CODE]
I have found on Googlu tha gif interface is ip tunnel, but tun interface is what according that? How is possible to configure those interfaces in Cisco ASA?
Last thing I don´t understand is a logic in those NAT commands:
[CODE]map xl3 from aaa.aaa.aaa.aaa/24 ! to bbb.bbb.bbb.bbb/13 -> ccc.ccc.ccc.ccc/32
map xl3 from ddd.ddd.ddd.ddd/24 to any -> eee.eee.eee.eee/32 portmap tcp/udp 20001:30000
[/CODE]
Thank you very much,
Mark
