understanding asa config statement
Posted on 2014-09-25
Im creating a vpn tunnel and here is the config below from the ASA. Next to some of the statements I wrote in parenthesis what I'm thinking each statement actually means, I think I have a pretty good idea but I would appreciate any help in someone explaining anything I'm missing or explaining it better. Thanks.
access-list outside_cryptomap extended permit tcp 10.10.10.0 255.255.255.0 any object-group DM_INLINE_TCP_1
(This access list shows the interesting traffic from the inside 10.10.10.0 network to anywhere. Why does it again show the object-group DM_INLINE_TCP_1 which is the inside network of 10.10.10.0)? Is there a way to remove the "DM_INLINE_TCP_1" from the cli?
nat (inside,outside) source static 10.10.10.0 10.10.10.0 service tcp_http tcp_http no-proxy-arp
nat (inside,outside) source static 10.10.10.0 10.10.10.0 service tcp_https tcp_https no-proxy-arp
(My goal is to not have the interesting traffic nated. So why does it sat "nat" and not "nat0"? Also since my source and destination address\network is the same does that mean it is nating its self, its own address?)
crypto map outside_map 1 match address outside_cryptomap (this is the acl from line 1?)
crypto map outside_map 1 set pfs group5
crypto map outside_map 1 set peer 220.127.116.11
crypto map outside_map 1 set ikev1 transform-set AES-256_SHA
crypto map outside_map 1 set nat-t-disable
crypto map outside_map interface outside (this is the interface in which the vpn extablishes or encrypts the traffic on)?
