Cisco Firewall :: 5510 - ASA 8.2.5 To Make VPN Connection From LAN To Outside?
Sep 19, 2011
i have a 5510 with SDM 8.2.5 from clients connected to LAN i cant open a VPN connection! (using windows client L2TP or PPTP) there is not rules tho block this ports, why i cant connect?
I have turned on the aaa command authorization without applying adequate privileges to the user. I can now log in through that user but the ASA 5510 displays an error :ASA 5510# show running-config
I am unable to make any configuration changes on the firewall. Is there any default user through which I can log in and disable the aaa authorization ? if not, how can I resolve this situation ?
i have router 3845 and then it's connected with pix and then its connected with vpn tunnel to the customer router. i am here trying to make vpn connectivity for devices. so on router i did static nat statements 10.124.90.124 10.200.200.1. this type of six statements i wrote for six devices. on the pix i did
i have one question that i need to use physical subnet or nat subnet for crypto map acl? and also on the customer router which subnet they can use as well nat sunet or my router physical subnet?
I have just put an ASA5510 in place and have the following setup:
Interface Ethernet0/0 nameif outside security-level 0 ip address dhcp setroute
[Code]....
I have connected my stations to an ESW540 inside of the Int Eth0/1 and am able to get ip addresses to the stations as well as DNS addresses. I cannot however connect to the outside connection in any way. From a computer connected to the ESW540 with a DHCP assigned IP address, I can ping the computer's IP, the ESW540's IP, and even 192.168.15.1. But I cannot ping the ip address from the Int Eth0/0, nor anything beyond 192.168.15.1.
From inside of the console of the ASA, I can ping all addresses of all ports as well as devices outside of the building and inside of ESW540.
I recently had a firewall that wasn't passing traffic (ASA 5510 running software version 9.1).It turned out it had 130000 active connections. Doing a "clear conn port 53" dropped the active connection count back to 38k, and the firewall started passing traffic again.
i've two cisco asa5510 with 4 FastEthernet interfaces each.They are connected as below:
[code]...
to three different ISP each of them! The 4rth interface of each of them, is connected to internal LAN network. Both Firewalls, offers VPN Services to ISP connections on Fa0/0
How can i achieve high availability for this scneario?is this possible to implement some HighAvailability and to offer the actual services to each of them, in case that the other firewall fail?What about using subintefaces? can i connect bothe ISP and Customers links on one or each of them, in case that firewall01 fails, all the services to be online on firewall02?
1) Will I be able to update firmware (from 8.2 to 8.3 or higher for example) without smarnet for ASA 5510? And what can not I do without smartnet? 2) I have only AIP-SSM-10 module to this asa 5510. is there a smartnet for it, too? And when I buy only module is there build in a 1 year subscription for IPS signatures? 3) If I have Cisco ASA 5510 base license, will my IPS on AIP-SSM-10 work? 4) Also I'm planning in a year buy one more 5510 with same module and put ther in failover. Will I really need Security Plus license for failover (Active/Standby)? For Active/Active I know that I need one, yes?
I had an experience this week of installing a 5510 ASA with 8.4.3, also tried 8.4.4(1) with the strange effect that I randomly was losing contact with the internet. The interface stayed up/up. no errors or what so ever on the interface. Reseat of the DSL wire no result. Reseat of the outside interface cable made it work again. And after some time lost connectivity again. It did not recover by itself so had to let someone do a reseat again and again and.... The outside was using DHCP client. A lease was given and an IP also. Nothing strange to find. Talked to the provider which could see the DSL and the DHCP lease. Finally I downgraded the firmware to 8.4.2 and the problem was solved.
I am replacing an old Fw with a New ASA 5510 and I have a problem with a TCP Connection on My LAN InterfaceI joined a picture of what I want to do. [code] From the PC,I can Ping the Video Camera But I can't connect to it with HTTP.I don't understand, Packet Tracert allow the Http packet too. [code]
I got a Problem on a customer which is using a Failover ASA 5510 pair with SSM-CSC-10-K9 modules.The clients have to connect to a webserver where they are doing some calculations.If they prepare everything and want to calculate everything what takes a couple of time the session is after about 3 minutes timedout.My first idea was to set session specific timeouts which are a bit longer then the normal but this setting did not work. I created a policy which did not work for me. How to set connection specific timeout's? [code]
I am configuring a new ASA 5510 to replace a SonicWall and I have a problem with an HTTP Connection inside my LAN.PC from the LAN ( using ASA LAN interface as gateway) can't Connect to a Camera video Web Server (192.168.4.20) on Port 80 whereas I can Ping it.
ADSM logs show :
106015# Deny TCP (no connection) from ip1 to ip2 Flags RST on Interface LAN.The adaptive security appliance discarded a TCP Packet that has no Associated connection in the adaptive security appliance Connection table.
- I Enabled command "same-security-traffic permit intra-interface"
- HTTP inspection is disabled.
I used Capture feature on the Ingress Interface, I joined the Logs and a part of my ASA Running Config.
we have installed an asa 5510 with 3 interfaces : dmz (web server 172.20.0.59;application server 172.20.0.58; server mail 172.20.0.157), inside (lan) and outside (connected to a router for internet connexion). the problem is that the connexion internet is slow in the inside (lan). our dns is in the ouside with ip address x.x.x.60 ( the dns have translated addresse to inside and dmz 172.20.0.60). the router connected to our IPS have x.x.x.33 (our default gateway for internet). there is a simple switch between firewall and router. the inside interface of the asa is connected to catalyst cisco 6509 (the interface gigabit of the 6509 is configured to auto speed and duplex). the asa have base lisence.here is the configuration of the asa and the output of commandes show interfaces (inside, outside), show asp drop , show perform.
firewall# show run ASA Version 8.2(1) ! hostname firewall domain-name xxx.xx enable password dgft12ghkHKM123Z encrypted passwd dgft12ghkHKM123Z encrypted names
I have an ASA-5510 in a location that loses connectivity to the wan gateway after anywhere from five to fifteen minutes. At first I thought that the unit might be defective, but I replaced it with an ASA-5505 with similar results. A reload of the ASA-5510 will restore connectivity for the next quarter hour.
Here's the version information on the 5510:
Cisco Adaptive Security Appliance Software Version 8.2(1) Device Manager Version 6.2(1) Compiled on Tue 05-May-09 22:45 by builders
I am using ASA 5510 and I have a specific problem with Http Connection to receive a video Flow ( RSTP protocol ) in the LAN. Some Pc users (192.168.1.133,in the log) with ASA Lan Interface as gateway can ping the Camera but don't receveive the video flow.Some Pc users (192.168.1.116,in the log) using another gateway can ping and receive the video flow. I used Whireshark to capture traffic between camera and Pc using the 2 gateway. I joined Logs with this message.It seems to be a problem of TCP segments on the ASA, I try to changed some TCP options but it's still the same:- Disable Force Maximum Segment Size- Enable Force TCP Connection to Linger in TIME_WAIT State for at Least 15 Second.
so i have a ASA 5510. The ASA is Connect with the Internet through PPOE DSL MODEM
The outside Interface get an IP. The Inside Interface get through DHCP from the ASA the Internet DNS SERVER (T-Online) But the HOST do not connect to the Internet because the DNS Server is timed out
I am managing a firewall setup with some ASA 5510's.One of the rules I have in the ACL list is to allow or deny (By disabling the rule) access to certain subnets.
I have a 3rd party vendor that from time to time need access to specific servers in the infrastructure, but I want to keep a certain level of control when they can access them and especially when they can not.
I know it works fine, I have done several tests to verify when they can connect and when they can not. But, now comes the tricky part, if they are already connected (Remote desktop) to the system, and I disable the rule, they are STILL!!! connected. It seems the firewall does not terminate the active session / cconnection when I disable the rule allowing them access..
Using Cisco ASA5510 Security Plus (Post May 2010) with 8.2(1)
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?
Currently, my customer has 2 units of Cisco PIX 515E running on Active/Standby mode. As for the heartbeat link, there are 2 dedicated switches placed in between both the Cisco PIX 515E i.e. FW1 --> SW1 --> SW2 --> FW2.
My customer will be changing both the Cisco PIX 515E to Cisco ASA 5510. Now, they are asking me, since they will be using Cisco ASA 5510 eventually, can the heartbeat link be a direct UTP cross cable or must the 2 switches in between still exist?
I remember I have tested this before, few years back, in the event I were to pull out the UTP cross cable that's connecting both the Cisco ASA 5510 Firewalls directly (without any switches in between), the Active/Standby mode still works fine. It doesn't go bad whereby both the Cisco ASA 5510 suddenly becomes Active/Active, and causes network issue.
Are switches required for the heartbeat link in a Cisco ASA environment or can a direct UTP cross cable connection be adequate.
Our client tried to a download a real time generated file from a website, the generation process around 5 mins, after 5 mins, the file will be started to download
When my client direct connect to internet, the file can be download successfully, but when pass through the ASA 5510 and using the internal IP address, a message something like "Are you sure want to logout from this web page?" appears in Safari after 5 mins, i think the time of the error message appear when a "you can start to download" message send from the server to client, the page session timeout so that make the user cannot download the file from internet as the session is not vaild.
I couldn't find any timeout setting in "show runn", is it possible the setting in ASDM? how can I find it and configure it?
ASA 5510 ASA 8.0 ASDM 6.1 I want some remote users to have split-tunnel connection, others not. I used Cisco Document ID 100936 "Allow Split Tunneling for AnyConnect VPN Client on the ASA Configuration...". I created a new Group Policy with split-tunnel enabled. I created a new Connection Profile and assigned to it the new Group Policy. When I authenticate at the AnyConnect client I get a dropdown of the 2 connecton profiles, to choose the one I want. Each of them works, enabling or disabling split-tunnel. But I want to assign a connection profile to the particular user, not give the user a choice. The problem is I'm using LDAP authentication. The Local Users I set up before LDAP are obsolete, assigning them a Group Policy does nothing. I really don't want to give up LDAP and force people back to another local password. But the LDAP authentication to Active Directory just says yes or no, it won't assign a connection profile. At the AnyConnect Connection Profiles page I have set a switch "Allow user to select connection profile, identified by its alias, on the login page. Otherwise, DefaultWebVPNGroup will be the connection profile". If I clear that switch every user will be assigned the same default profile, which does not work.
I am trying to confgure a VPN connection on a Cisco ASA 5505, and I am supposed to translate the inside network from 10.200 76.0 to host 10.1.4.204, and then from that scheme establish a VPN with the host 66.179.80.108 on network 192.168.50.0/24. I was told that this Cisco ASA appliace would be able to translate the network address as a mask in order to make the necessary connection with the other site connection.
I will be implementing a new firewall (cisco asa 5515x) on my existing 3750x (server switches) and my 2960s (user switches). What should I need to apply on my firewall and swtiches to make the implementation successfull. I will put my 3750x as my DMZ and my 2960s as my inside. The 3750x have multiple subnet and also the 2960s.which features and technologies i need to know on those 3 products. my 3750x and 2960s don't have any ACL defined and most common features are vlan, switchport, trunking, spanning-tree, stacking, vtp.how my asa knows that my 3750x/2960s have multiple vlans. my current connection right now on 3750x and 2960s is just through 6 ports i assigned as one trunk, below is my config [code]
my 2960s vlans are almost the same with my 3750x except vlan 160, 170, 192. but of course when i put this in asa, i have to segragate vlan for 3750x (192, 100, 110,160, 170) and 2960s (130, 150). for my 2960s connection to the asa and since this will have big bandwidth, i will use 3 ports on my asa (and trunk it) connecting to my 2960s and i will use 2 ports on my asa (and trunk it) connecting to my 3750x. the one internet ports and my one management ports on my asa will stay like that.
How many concurrent SIP channels should I expect to be able to make through a PIX firewall? We currently have a PIX 515 with the SIP fixup enabled.it worked fine for a low volume of traffic, but once we got to around 400-500 concurrent SIP calls the PIX started to struggle. Calls were dropping and other Internet traffic was intermittent. When I decreased the call volume it recovered and everything returned to normal.Bandwidth wise, we were only using about 20MB, so I think that as it needs to inspect and remember SIP packets for the purposes of opening RTP ports, we probably hit a bottleneck in terms of either the PIX's CPU or memory capacity. I've not seen any specs detailing how many SIP fixups a PIX (of any capacity) is able to handle.I'm thinking of upgrading to a PIX 525 or PIX 535, but I'd like to know how many SIP calls they will be able to handle before committing.
Should i get a wireless adapter Or a wireless repeater Which would be better for a better connection?My router is down stairs and my xbox is upstairs.I could get the wireless adapter upstairs then do an ethernet cable straight to my xbox.
I'm using XP SP3. I'm trying to connect using the Local Area Connection for the first time. Up to now I've been using wireless but I'd like to get better performance.
Here are my current settings via IPconfig: Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . :
[Code].....
I've tried releasing and renewing via IPconfig. Renewing gives me the following error message: An error occurred while renewing interface Local Area Connection : unable to contact your DHCP server. Request has timed out.
I've got limited connectivity. It's trying to send but cannot receive.
My laptop used to connect wireless very well. About 10 days, it lost the connection even though the wireless signals were excellent. I guess it might be due to a virus attack that disabled my wireless connection. I run System Restore on Networking but not successful.
