I Changed my old firewall by an ASA5510, since that change my internet connexion is slower.Some websites takes longer to display.I would like to know if there are some specific configuration about TCP connection or DNS to setup?
I just configured the ISP DNS :
Dns server-group DefaultDNSname-server 194.2.0.20 name-server 194.2.0.50
Trying to get a service setup with a third party to access our system (ERP web service to access our ERP data, making data available to customers and vendors via internet). They require that I setup four external IP addresses to have access through the firewall. I haven't figured out how to do this. I'm using a Linksys WRV200 router.

How do I do this? I know how to create NAT… just not like this.
Recently implemented an ASA5510 and I cannot setup RDP access. I've browsed these and other forums and tried all the suggestions that I've been able to find and still no luck.

Is this supposed to be like this?So right now i can only access the management port when i'm in the same subnet.

I have two ASA 5510 running ASA ver 8.3(2) and ASDM 6.4(1). When I add static routes to the primary ASA the routes are not sent to the failover ASA. Is this to be expected or do I have a bug?
View 10 Replies View RelatedHave a 5510 in Routed mode, simple Static NAT to interface two networks (inside_1 is my private space, and outside_1 the larger intranet that hosts heavy traffic). outside_2 faces internet via pppoe just for VPN purposes.
It was operating fine for one year then one port broke (outside_2, internet), leaving no vpn. We followed RMA service replacement and the new unit came with upgraded SW (8.0.4) than the one the original config was created on (8.0.2).
To ease the replacement, I did downgrade the sw boot image. Then I did restore the config by tftp to the startup-config and then a reload. Everything seems to load fine.
Problem is that testing reveals some sort of issue: I can ping some of the intranet hosts but can't reach gateway, thus larger segment of hosts become unreachable. It seems as if the NAT mechanism can't find the next gateway where to hop. For debug practice, I've enabled all the icmp stuff so ping wasn't being blocked by the device.
Being given the fact that this config was up and running prior to the replacement, I've no reason to suspect any mysconfigured items (ie routes, NAT, access-list), but obviously I'm obfuscated and can't see what else I'm missing.
How is that possible that the PING only reaches certain hosts? Pinging to 10.15.5.90 works (Route is 0.0.0.0 0.0.0.0 to 10.15.5.126 (gw)), but pinging to the gateway itself doesn't (10.15.5.126) and even worse, hosts like 10.15.167.210 do not respond either.
I'm having a cow of a time trying to implement a NAT configuration after having upgraded our ASA5510 recently from IOS 8.2 to 8.4. The upgrade went fine, however we now have a need to add a new NAT rule and I'm not sure whether it's possible.
The upgraded NAT rule and access list works fine at allowing external access to a web server.
However we now need to NAT the SOURCE address (either to a pool or single address) of incoming http requests before forwarding the request to the server. Hence the server will see all requests as originating from a pool with a route heading back to the ASA. The basic issue is that the severs default gateway does not return to the ASA, so "tagging" the source address of external requests to an address or interface associated with the ASA should allow the server to return the traffic to the ASA. I know we shouldn't be doing it this way but we can't see any alternative.
Having read a huge amount of examples we can access the server with the above config (or Object NAT), and we can NAT incoming traffic,however we can't combine the two by having all external http requests Source Natted before forwarding to the server.
We are replacing our EOL Watchguard X1000 Firewall(s) with Cisco ASA 5510 unit - ASA Version 8.4(3). Following is the static NAT I have build and the corresponding access list.
nat (FW2Inside,FW2Outside) source static BW_XSP1_Private BW_XSP1_Public destinat
ion static BW_XSP1_Private BW_XSP1_Public
access-list FW2Outside_access_in extended permit tcp any object BW_XSP1_Public object-group DM_INLINE_TCP_1
Unable to access the server on the inside interface via the public NAT address. Can you point me in the right direction as to what I might be missing to make this work?
I'm trying to track down the installation and configuration procedures for the common criteria EAL4 evaluated ASA5510 but not having any joy.
The ASA Release 8.3.2 certification report [URL] identifies the required configuration documentation as the "Cisco Adaptive Security Appliances (ASA) Firewall and Virtual Private Network (VPN) Platform Common Criteria Operational User Guidance and Preparative Procedures" but I can not find any reference to this on the Cisco web site.
So far I've only been able to locate the proceedures for the older 7.0 release. [URL]
How to locate the correct documentation needed to configure an ASA5510 to achieve the common criteria EAL4 evaluated configuration.
When I try to save the configuration it displays the following error.Is it due to insufficient memory?

I try to setup a ASA5510, but without success. Actually, I have Cisco1800(192.168.96.1/21) from my ISP connected to a Cisco 3825 (via port with IP 192.168.96.2) all is working good. Now I want to insert a asa firewall between ISP router and 3825.
For that, I tried a more simple config :
ISProuter (192.168.96.1/21) ---- ASA outside port(192.168.96.2/255.255.255.248) ASA INSIDE port (192.168.100.1/255.255.255.0) --- a pc with IP 192.168.100.2, netsmask 255.255.255.0, gateway 192.168.100.1
From my ASA, I can ping 192.168.96.1. but a "ping INSIDE 192.168.96.1" fail
from py pc, can ping 192.168.100.1, but not 192.168.96.1
Here, my ASA config :

I am trying to set up SSL VPN with two-factor authentication on an ASA5510 with software version 8.0(4). I want to use LDAP for actual authentication and user mapping, but require a valid certificate signed by a particular local CA to connect.I have imported the CA's root certificate, signed an identity cert for the ASA box and imported, and assigned the cert ("trustpoint") to the outside interface.Under the connection profile itself (for DefaultWEBVPNGroup), there is an option to select authentication method as AAA, certificate or both. AAA works as expected, authenticating against LDAP. If I select certificate or both, I get rejected with Certificate Validation Failure regardless of if I have a valid signed cert or not. This is what I see with "debug webvpn 100":
webvpn_portal.c:ewaFormServe_webvpn_login[1904]webvpn_portal.c:http_webvpn_kill_cookie[682]webvpn_portal.c:ewaFormSubmit_webvpn_login[1964]ewaFormSubmit_webvpn_login: tgCookie = 0ewaFormSubmit_webvpn_login: cookie = c98f3940ewaFormSubmit_webvpn_login: tgCookieSet = 0ewaFormSubmit_webvpn_login: tgroup = NULLTunnel Group: DefaultWEBVPNGroup, Client Cert Auth Failed!Embedded CA Server not enabled. Logging out the user.webvpn_portal.c:ewaFormServe_webvpn_login[1904]webvpn_portal.c:http_webvpn_kill_cookie[682]
So, it seems the ASA is only trying to check the cert against a (nonexistent) ASA-based CA. How do I get it to check against an external CA cert?Under "Remote Access VPN -> Network (client) Access -> AnyConnect Connection Profiles", I have ticked "Allow Access" and "Enable DTLS". There is also an option "Require client certificate" which doesn't seem to do anything - whether or not I check it, I can connect and authenticate to the VPN with or without signed certs as long as the previous setting is "AAA".
Some highlights from the config:

View 3 Replies View RelatedMy setup has two firewalls to the internet, one is for all internal users who want to access the internet and the other is an ASA5510 acting as VPN terminaton to remote workers accessing using Anyconnect.Each of the firewalls has a public interface on the same network (ex. 196.160.100.192/26).We have a server with a public interface, and all traffic (internal and external) has to access via the public ip (again in the same network as above) and there are different profiles and access levels on that server depending if you are accessing from an internal IP or a public IP.Well, when users are connected thrugh the VPN, although they have an internal IP address, as they are accessing the server on the public IP, the ASA sends the packets through its external interface (direct connected route) instead of sending it to the default internal gateway that is a "trusted" entry point on the server.Any way to force the ASA to send that traffic to the internal default gateway instead of sending it to the external (direct connected) interface?
PS: I have no access to the server (appliance under warranty) so I can't make any changes to it...
I have a monitoring rule that checks the number of connections on the firewall using the following command: show conn count
My results are always between 3,000 and 9,000.A while back, I had an issue where all 130,000 connections were being used up. I configured a service policy to limit the number of connections between any two end points.
I'm monitoring the error logs and I'm noticing that my connection limit rule is being triggered on a regular basis. I receive the following message.Per-client connection limit exceeded 20000/20000 for output packet from x.x.x.x to x.x.x.x on interface outside
I'm confused as to the difference between the connections limited by my rule and the connections shown by "show conn count". why I never see any connections higher than 9,000 using "show conn count" yet I am seeing alerts stating that the firewall has reached 20000 connections?My firewall is an ASA5510 running.
I'm about to setup as ASA configuration with GNS3 ASA. how to best test the configuration once complete? I need something like a verification plan to ensure that the configuration would perform if in production.
View 1 Replies View RelatedOur ASA 5510 is running 8.0(5). We recently upgraded the license from base to security plus. By doing so the capacity of the the external port Ethernet0/0 and Ethernet0/1 should increase from the original FE to GE. But, we were still seeing 100 Mbps on our Ethernet0/0 interface. We figured that out that the provider switch is only supporting 100 Mbps which is a bottleneck for us.The provider will be upgrading there switches to 1 Gb switch.
We will have to swap the switch connections now from 100 Mbps to 1 Gb switch.What commands should we be familar ourself with?Though this will be doine in our maintenace window.All the transaltions/connections will be dropped in our production environment so we are kind of scared.
Everything was working fine till one day, when clicking on Configuration Button you see setup wizard prompt.It's ASDM ver:6.2 and ASA 8.2. Everything is working fine, but now unable to change any rules.
It there simple cure for that?
I have ASA 5510 with 8.2.4 and 8.0.x OS and all seem to have common problem of idle TCP connections not timing out. The host to host connections are coming over VPN tunnels. I have default timeouts on all the firewalls. I have tried changing global timeouts and as well as host specific timeouts using MPF but doesn't work at all ! The problem is when TCP connections are sitting idle in conn table for days and when connection limit of 50,000 conns reach the firewall starts behaving unpredictably dropping packets or unresponsive! I need the unused idle connections to timeout which is NOT happening either by changing global values or MPF.

View 3 Replies View RelatedI have been having an annoying issue for the past few weeks with my ASA setup. We are using the ASA as our Remote Access Gateway and originally had it setup in a Active/Standby failover configuration using 2 x 5520 ASA's.The original setup of the devices was that the 2 x ASA were setup in a failover configuration, with both of them connecting back to the internal network via a 6500 device. Because of using failover I created a VLAN on the 6500 and put the two ports that connect the ASA's into that VLAN. I then configured the VLAN interface to be the EIGRP interface for the neighbour relationship to the ASA's.
The problem I am seeing is that the EIGRP neighbour relationship between the Active ASA and the 6500 keeps flapping. It occurs abour 4-5 times every day at randmon intervals. Sometimes the neighbour relationship will stay up for 6-7 hours, other times it flaps every 1-2 hours. I initially thought it was due to the failover configuration so I removed one of the ASA's and removed all of the failover configuration, but the EIGRP neighbour flapping problem still exisits. [code] Since removing the failvoer configuration I am thinking it could be a physical cable problem?
We have 2 ASA 5510's setup in an active, standby failover configuration. When the primary fails over to standby, the 3rd party cert does not failover to the standby ASA. The users then receive the CERT missing, invalid message and have to select yes, no to move on. This does not occur when the primary is not in failover mode. It is my understanding that failover fails over certs but in our case it does not apper to be working correctly.
