Apr 29, 2012I have an ASA 5520 with the below config
Gi0/0: outside (Internet)
Gi0/1: inside (Internal users)
Gi0/2: DMZ (web servers, ftp, Mail etc..)
I have a SMTP relay deployed on the DMZ for mailing. I have also a mail servers installed in the internal lan,
I want to allow trafic from dmz to reach internal lan, and i want normally also allow stmp relay from dmz to reach Internet.
How can i block trafic from DMZ to reach Internal Lan (instead of smtp) if the to allow trafic from dmz to internet i must put ANY in the policy?
For allowing trafic from DMZ to reach Internet, the policy must be DMZ -----> ANY ----->Services., this policy means DMZ can implicity reach Internal Lan?

Feb 27, 2013I'd like to see some REAL LIFE comparisons of ASA firewall throughput (a bit like this one for ISR G2 Routers - [URL].
The reason I ask is that I recently upgraded a firewall from an ASA5505 to an ASA5520 on a small network where the only outside connectivity was a single 10meg Internet circuit with an IPSEC VPN (not landed on the firewall but on a router) to another site.
When I swapped out the firewall the users noticed a big improvement. The firewall is not doing anything out of the ordinary - no IPS or VPN, just standard state full inspection.

View 3 Replies View RelatedCisco Firewall :: 5505 - Block Everything Except A Few Ports
Apr 15, 2013We have a client that is running a PC on a internet over satellite. To avoid any unessecery traffic over the satellite link (data traffic is quite expensive), we've suggested to use a 5505, as we had one handy already.
So basically what we wanted was to block everything outgoing and everything ingoing, except for example port 22 (ssh).
But I'm struggling a bit, since this is my first cisco router to be configured.
My interfaces are as follows.
Outside - DHCP
Inside (port 1) - 192.168.1.1
I'm only running ipv4.
in ASDM I made a static NAT rule for port 22, being forwarded to 192.168.1.5 (the computer)
in Access rules I made under outside (incomming rules) source=any destination=outside service=ssh action=permit
But when I try to add further rules to block everything else, it takes the SSH on port 22 with it. How should I do this the easiest way?
the hardware setup is pretty straight forward.
sat-terminal(with IP 192.168.0.1 running DHCP) -> 5505 (outside IP=DHCP - inside IP=192.168.1.1) -> computer (IP=192.168.1.5)

View 2 Replies View RelatedCisco Firewall :: 5520 Identity Based Firewall Doesn't Work Using Citric Published
Jul 26, 2012We are using the newest release of AD Agent (1.0.0.32.1, built 598). The ASA Firewalls 5520 are having the software release 8.4(3)8 installed.When somebody tries to connect thru the Identity based firewalls from a citrix published desktop environment (PDI) the connection is not possible. Checking the ip-of-user mapping on the firewalls (show user-identity ip-of-user USERNAME) mostly doesn't show the mapping of the USERNAME and the PDI the user is logged in. The user-of-ip mapping of the PDIs IP-address shows mostly other users, which then are used to authenticate the acces thru the firewalls.
What is interesting, that on the AD Agent using "adacfg.exe cache list | find /i "USERNAME"" i can't see the PDIs IP-address neither because it is mapped to another user.Is Citrix Published Desktop environment supported to connect thru Identity based Firewalls? How AD Agent, Domain Controllers and Firewalls are working together? On the firewalls with "show user-identity ad-agent we see, the following:
-Authentication Port: udp/1645
-Accounting Port: udp/1646
-ASA Listening Port: udp/3799
Why Cisco does use 1645 and 1646 and not 1812 and 1813?The Listening Port is used for what purpose? we tried the AD Agent modes full- download and on-demand with the same effect.

Apr 15, 2013I try to launch a LAND Attack against my firewall ASA 5520. Everything will work fine. But why, I think it should not work. I use a little tool where I can user a spoofed address, with a cluster shell and attack the firewall interface with the source of 127.0.0.1 ore the ip address of the interface as the source and destination. Then I get a cpu load of 89% with only two host. With IP tables I can use kernel processes to prevent this. But I don´t find anything for ASA.
