I have a problem with my ASA5505 after enabling botnet filter my ASA reboots.Also while booting it usualy takes around 30minutes of random cycles before loading the OS. It seems to be falling at the license check.To fix the boot I usualy unplug the ASA for about 15minutes and then it will boot up fine.

We care currently using an ASA5505 as our firewall and redirecting web traffic to a S160 Iron port. Recently the web filter stopped working and the only way to get filtering again is to reset the redirection.
1. Is there any available log information to find out about the WCCP process and maybe way it stops?
2. Are there keep alive packets or anything of that natural between the ASA and Ironport?
in my test LAB i have used a 5505 running 9.1.1.I have setup a DC (2008R2) and then AD Agent.I have configured and used Identity firewall rules which worked like a charm.I have also used LDAP Auth which also worked fine.I then disabled all the rules but kept the identity firewall checked.Since it was a lab environment, i had to remove the DC for other tests.A few hours later the ASA initially was stuck.I used the console and i saw it could ping noone! not even directly attached PCs or defgw (i was able to ping them before it stucked).No arp table also!the asa did no NATing so no xlate entries were vavailable.Then i sshed to it.I got a blank screen and from console i could see cpu-usage from ssh to 20%I opened a second ssh: nothing. Blank Screen again. cpu-usage from ssh to 40% (overall ~50%)I opened a third ssh: nothing. Blank Screen again. cpu-usage from ssh to 65% (overall ~75%)I issued reload from console! Nothing! it was trying to shut down!I issued reload quick-> that is when console was lost!!I have to unplug it.
The DC that was removed was also the DNS for the ASA.The only log message i could see, before it stuck was "AD Agent is out of reach".i have ttried this 4 times. Always the same. 100% reproducible.I disabled the identity firewall-> no problem! it worked for days.100% reproducable.I downgraded to 8.4.5--> the same for both above actions.

View 15 Replies View RelatedI have two ASA5510's set up in failover, and the secondary keeps crashing after doing the interface checks when bringing failover up. This only happens if I try to upgrade the image on the secondary to anything newer than 8.4.1 (I've tried with 8.4.1-11 and 8.4.2). The primary one run just fine with new images.
I don't have the exact error right now, as I need to do a screen capture from console. It's just a huge crash dump.Are there anything I might have missed during the upgrade? Should I cold-boot both the firewalls in the correct order?

View 4 Replies View Relatedwe had just installed our ASA 5550 with IOS 8.0(2) a couple of week ago.
2 interfaces from each slot are being used ie 0/0 for Branch users comming via MPLS cloud , 0/1 for internal LAN users comming form Core Switch & 1/0 for Server farm LAN , 1/1 for Internet (outside)
the first 3 interface are considered inside with sec set at 100 while the 1/1 is outside with sec at 0.
Last night it suddenly started dropping all connections without any warning or any noticible log form the ASDM logging.
the connection drop would happen for 2 - 3 minutes and would work fine for the next 15 minutes or so..
after conencting the console , we found out that the IOS would suddelny go abrupt and show this display ...

View 3 Replies View RelatedI've got a PIX running 7.2(4) with its outside interface on the Internet. The only thing this PIX is doing is acting as the endpoint for an IPSEC LAN-to-LAN tunnel with an Internet-connected ASA on another network.
I'd like to filter inbound Internet traffic to this PIX so that only the designated ASA can attempt to establish an IPSEC connection -- in other words, I want to prevent any other device on the Internet from even being able to attempt to establish an IPSEC connection to the PIX. As far as I know (and have seen), this can't be done with an access-list on the outside interface, since that access-list doesn't apply to traffic to the PIX itself.

View 1 Replies View RelatedI am currently trying to enable WCCP between a Cisco ASA 5512 firewall and Barraccuda Webfilter 410 Vx applicance. The ASA firewall is running IOS version 8.6(1)2 and the Barracuda is funning firemware 6.0.0.013. Both the ASA and Barracuda are in the same network and can ping eachother. The ASA has several interfaces, outside, inside, data and dmz. The PCs and barracuda appliance are behind the data interface. ASA data IP 172.16.18.1 Barracuda IP 172.16.18.40 All PCs in the 172.16.18.0/24 subnet use the ASA as the default gateway and should have web requests redirected to the Barracuda.
Below are the respecive bits of my ASA config

I suspect my issue is that the ASA is generating a Router Identifier of 172.21.20.1 which is my inside network and the barracuda cannot communicate with it. how I can get this working ?

I was trying to limit the number of internet IP Address that can initiate Remote Access VPN connection to the firewall. I have plan to only allow internet IP Address from few ISPs for control.
However, blocking AHP, ESP, ISAKMP, NON500-ISAKMP, and IPSec Over TCP Port Assigned in the firewall outside interface doesn't work. But it works by putting the ACL in the router before the firewall. It seems that the firewall have a "hidden" process VPN first before user entered ACL (or explicit rule), similar to Checkpoint FW's implied rule. How to get around it?
How does a firewall block or filter traffic on a specific port or IP address?
View 1 Replies View RelatedI was having major issues with a 5505 (too long a discussion to go into here) so I formatted the disk and uploaded fresh binaries and recreated my configuration. I noticed the licenses were preserved. I also noticed there were several fsck records after the format that were reclaiming lost chains. I suspect the flash on this ASA is going bad, since everytime it boots it says "reading from flash ..!!" like it cannot even read flash successfully. When I purchased this one new, it also had several fsck records being brand new. I'm going to open a case on these flash issues/questions.
Anyway, after all of the above, the only thing that is not working is the botnet filter. [code]

View 9 Replies View RelatedI have a normal setup of ASA5505 (without security license) connected behind an internet router. From the ASA5505 console I can ping the Internet. However, users behind the Firewall on the internal LAN, cannot ping the Internet even though NATing is configured. The users can ping the Inside interface of the Firewall so there is no internal reachability problem. In addition, I noticed that the NAT inside access list is not having any hit counts at all when users are trying to reach the internet.
When i replace the ASA5505 with a router with NAT overload configuration on it, the setup works normally and users are able to browse the internet.
The ASA5505 configuration is shown below.

View 2 Replies View RelatedI've recently upgraded my old firewall from a PIX to an ASA5505 and have been trying to match up the configuration settings to no avail. I have is that I can't ping the new firewall on it's inside interface, despite having "icmp permit any inside" in the running config. Secondly, the server I have on there ("Sar") can't connect out to the internet.I've included the ASA's running config incase anybody can see if something stands out. I have a feeling it's either not letting anything onto the inside interface, or there is no nat going on. Lastly (and possibly relevant), the firewall is actually going at the end of a vlan, which is different to the firewall's inside vlan number. I don't know if this is actually the problem because the server can't connect out even if connected directly into the firewall.

Juniper fe0/0/2 -> Cisco ASA 5505
Cisco ASA 5505 - >Inernal LAN switch.
1. Internet is connected to Juniper Ge0/0/0 via /30 IP.
2. Juniper fe0/0/2 port is configured as inet port and configured the Internal public LAN pool provided by the ISP. And this port is directly connected to Cisco ASA 5505 E0/0. Its a /28 pool IP address. This interface is configured as outside and security level set to 0.
From Juniper SRX, am able to ping public Internet IPs (8.8.8.8).
Issue:
1. From ASA am unable to ping public ip configured on Juniper G0/0/0 port.(/30)
2. From ASA no other Public internet IP is pinging.
Troubleshooting Done so far.
1, Configured icmp inspection on ASA.
2. Used the packet tracer in ASA, it shows the packet is flowing outside without a drop.
3. Allowed all services in untrust zone in bound traffic in Juniper SRX.
4. Viewed the logs when I was trying the ping 8.8.8.8 in ASA. It says "Tear down ICMP connection for faddrr **** gaddr **
I'm running into this issue on an ASA 5520 running version 8.2(2)9 and ASDM version 6.2(1).
I have an ACL denying traffic to a certain IP range and the logging level set to Debugging. The hit count is rising quite rapidly but when selecting "Show Log" the Real-Time Log Viewer opens with a value of 0x13d0ee2a in the "Filter By" field and no logs are ever shown.
Logging is enabled globally and Logging Filters on ASDM is set to Debugging as well.
how I can get the RTLV working?
I'm trying to troubleshoot an ASA5505.
The original goal was to block "Mumble/Murmur" (a voip app) traffic, which runs on TCP/UDP 64738, both inbound and outbound, except to a certain host (63.223.117.170).
However, when nothing I tried seemed to make a difference, just to troubleshoot, I decided to try blocking all inbound traffic. I first disconnected ethernet port 0/0 to ensure that it was cabled correctly and the outside interface went down when I did. That worked as expected, so I confirmed I had the right interface and it was cabled correctly.
I then applied a "any any deny ip" rule as the first element in the outside interface access_list, as you can see below. However, it appears to have had no real effect and the hit count is very low (it should be astronomical).
