Cisco Firewall :: ASA5525 / Got Warning Message When Configuring Nat On 8.3 And Later
Jun 11, 2013
I'm configuring the nat on a ASA5525 running on 9.1.2 and got 2 questions, 1. Is the below overlap warning message normal and will not cause any issue? 2. Is there a simple way on 8.3 and later to fulfill the same functionality like 8.2 and earlier?
old config on 8.2 and earlier
nat (inside) 1 0.0.0.0 0.0.0.0 0 0
nat (dmz) 1 0.0.0.0 0.0.0.0 0 0
global (outside) 1 216.19.84.5
I know the 5510 & 5520s support the CSC-SSM module for Content Filtering (Anti-Phishing, Anti Spam, URL filtering, Anti-Spyware & Antivirus), but what about content filtering for the ASA5525-K9.The problem that I have is that I need a firewall that supports up to 1 Gbps Maximum Firewall Throughput and to support 250 users with Content Filtering described above.I'm using the following doc for sizing and came across the ASA5525-K9 for 1 Gbps, but not sure about the Content filtering: url...
If ASA5525 with ASA8.6(1)2 can be browsed using ASDM7.0(1), as currently i'm running ASDM6.6(1) if it will work, any document how to do the upgrade using GUI screen?
i never see this before, but on newly purchased just configured firewall.when i do wrtie standby.All interfaces on standby unit flaps.is it some IOS bug? my firewalls are [code] what could be the reason? FYI i am using LAN base failover and not doing any statful fail-over.
Got an ASA5525-X with 8.6 release. We have an inside interface (10.11.1.0/24) and a DMZ interface (10.254.1.0/24). On that DMZ interface theres an SMTP server; by using the Public server feature in ASDM we created a rule so we have mapped the 10.254.1.29 internal ip to an external ip 217.x.x.x Everything is fine; working ok, but for several reasons we need to access the public ip 217.x.x.x from an inside ip (10.11.1.10). I tried to do it by creating an exemption for the dynamic nat; if i don't do that i have a 'deny ip spoof from...' message rolling on my syslogs.Seems to do the trick.....but only for pings! i ping the public ip from the inside ip, and got the reply from the internal ip on the DMZ. But if i want to telnet port 25 from inside to public; its not working.
My current ASA 5525-X is licensed with Anyconnect premium = 2 and 750 "Other VPN" What does other mean? Also does this mean that only two clients with Anyconnect can use the ASA for VPN? Or is Premium different than Anyconnect alone?
IPsec VPN configured between ASA5525-X and Linksys RV042 ,While transfering some exe from ASA5525-X side to Linksys RV042 side over VPN hash-sum of this file changes, so, when you open transferred file, you have an error message "File is corrupted". If you try to transfer file from Linksys side, hash-sum is ok. Also, work with oracle application is interrupted because of unknown reason. IPsec works only if using router instead of ASA.
used to use Ethernet connection on this pc for 2/3 years, i recently ran wireless for like 2months. every time i try and use Ethernet i get limited or no connectivity warning, I looked in my ipconfig, i notice theres no physical address or default gateway for my realtek rtl8139/810x family fast Ethernet.
We are using ACS 5.1 and from time to time we are getting a warning saying that the active sessions are over the limit (250000). It is just a warning, so my assumption is that its not a big deal, but how do we keep from getting the event, or prevent the event?
StartSSL offers free SSL certificates, so I'm guessing that means no Warning messages from browsers IE,Chrome,firefox atleast? Has anybody used this StartSSL certificate lvl1 is free..I'd tryed this myself but my hosting company is charging twice more for having ssl(just having it not even buying) than for hosting my website.
Using Windows 7 Pro. I get a yellow triangle with ! on the LAN icon. The message is : 'no internet access' but the internet works.On Network and sharing center, using work network, everything is ok.It doesn't happen all the time.
We have setup the IP phone proxy on our ASA-5520, we had a couple of issues with the initial setup, but nothing major. It has been up and running for a few weeks and basically everything works perfectly just like we designed it except for 1 strange audio issue on outbound calls. We can make a call to anywhere, no problem, if the call is answered, no problem, perfect call setup and good quality 2 way audio. But if the person we called doesn't answer the call and that call goes to their voicemail we loose all audio from that point forward, we do not hear their outgoing message or get any prompts just dead air. The same situation appears to be true for any "recorded" service on the other end of the call.
[LAN] <---> ASA 5520 <---> Cisco 2911 <---> [Internet] <---> Server A | | [DMZ]
Whenever I access a website running in "server A" (only HTTP traffic) everything works fine. The problem is that when I try to access a different service on the same server but listening on port 2000/tcp I get the TCP Reset-O message on the ASA and the workstation's browser says that "Internet Explorer cannot display the webpage".
A weird thing: if I access this service from a machine on the DMZ, it works fine. From the LAN (Inside) it does not work. The main difference is that from the LAN to OUTSIDE the ASA does NAT. From the DMZ to OUTSIDE it's just routed. I did another test from the LAN and the captured traffic is attached. I've been messing around with protocol inspects and firewall + NAT rules on the ASA but no luck at all.
I just deployed two stacked SG500X switches. I noticed these messages in the log (see below). Despite these messages everything appears to be functioning.

I've been getting warning messages from the event log of a 1300 series bridge, which is set as an Access Point in the network, states: 'Packet to client (mac address) reached max retries, removing the client'; I'm not sure why the client is removed. Does 'reached max retries' mean that the client has tried to many times to connect to the AP/Bridge?
i configured a new ASR1002 router yesterday,i powerd on the ASR1002 to check the device include some SPA moduler,but i found my console screen display like this""Warning: filesystem is not clean"and "%IOSXEBOOT-4-FILESYS_ERRORS_CORRECTED: (rp/0): bootflash contained errors which were auto-corrected."while ASR1002 power on.
i am able to connect to unsecured wireless networks but when i connect alll of them say no internet access i only notice a yellow warning sign beside those signal strength bars also and not on secured one !
On connecting VPN, i am getting this warning: Enabling VPN connection will block all traffic that doesn't get sent to this peer. After Yes, it stops all browsing. I want to access internet plus vpn connection.
I recently reboot my asa 5520, I was trying to remove webvpn listening from my outside nic, even though it wasn't configured. [code]I was planning to do another reload without the fast reload option.
I have an 887VA-w connected at home. I am using ip virtual-reassembly an all interfaces (dialer and all internal VLANs), I am also using CBAC (currently setting up ZBF). The issue I am having is that I keep getting drop packet error messages and the reasons can differ. Below are some of the outputs I recieve: [code] I have done a show ip virtual-reassembly on all the interfaces and the counter is shown as 0.
Two Vlans (ID1 and 100)are on a Cat 4500, which connects to an ASA, interface DMZ. On 4500, there is default route point to the ASA DMZ interface Issue, server on vlan 100 cannot ping a server on Vlan 1, vice verse. When I enable the realtime log, it gives me a “Translation creation failed” message, please see the attached files.
i got an error while connecting to my PIX (515e) via ssh connection there is an error message appears (The server has disconnected with error, server message reads: Internal Error) and at the console session at the time time, the following message appears also (process_create: out of memory)
When trying to access the asa (8.0(3)) with asdm the console send follwing error message:
vPif_isVpifNumValid: pifNum out of range! vPif_getVpif: bad vPifNum(0xa6) from 87EBC81 from 83833B4
Have a strong suspicion that it is a hardware failure (since asdm has worked and have tried to restart the box) can not see any errors with any show commands, but could it be a RAM error .
I am configuring a Cisco ASA 5505 firewall.In the office there is 1 x SBS 2008 server and 5 x PCs, all sat behind a Netgear DGN1000 ADSL router.We want to implement a ASA 5505 for added security.I have configured the internal interface of the Cisco ASA 5505 to be 192.168.0.1 - this is connected to local switch. The client PCs use 192.168.0.1 as their default gateway.I have configured the external ASA 5505 interface to be x.x.x.217. [code]Change the current router status from Router/Firewall/Modem to Modem only (Bridge mode). The ASA 5505 has its outside interface connected into one of the LAN ports of the netgear. The lan port has an IP of 192.168.0.254.
I'm fine tuning some of our ASA logging config, and am having an issue with one particular syslog ID.The message is: syslog 106100: default-level informational (enabled)and the log settings are:
This ACE log entry is generated by explicit deny any any statements at the end of all the ACLs, e.g.access-list inside_access_in extended deny ip any any log interval 600 Based on the config, I would expect to see this being logged to the syslog server, but not to the local buffer, but am still seeing them locally in the buffer:
It also still shows these as level "warning", %ASA-4-106100, instead of the default %ASA-6-106100 I've tried removing and re-applying the config at different levels but it still reports in the buffer log as level "warning", %ASA-4-106100 This also doesnt affect every 106100 log that is generated. Most messages are generated at the correct level 6 severity but some seem to randomly log at level 4. There doesn't seem to be any pattern to this. The same access-list line can produce severity level 4 and 6 106100 messages.
I have two ASA in failover with Active/standby configuration. When I switch from standby to active from the standby ASA I get a lot (like 100) of error messages like these below: [code] The failover works fine and nothing seems to be wrong with the firewalls function.
-Hardware is ASA5585-SSP-10. -Software version: ASA 8.2(5),
ASA is in multiple mode with 17 active context. Why these error messages appear and what they mean?
