I was configuring a device for one of our customers, but when I was setting up the MR3040's internet connection settings things went haywire.there's only a default selection for two of my country's providers. No biggy you'd think.
I am trying to figure out how to create an etherchannel with sub-interfaces on an asa 5520 running 8.4.1 code. It doesn't seem to allow me to configure any type of sub interface on the port-channel or anywhere else once I create it.
View 4 Replies View RelatedI recently implemented an ASA 5520 HA pair with CSC-SSM-20s in each non stateful per cisco. The CSC management sits in a management subnet 192.168.4.0/24 with the management interface of the ASA as its default gateway in the same subnet. Ever since the implementation frequently webpages will not load correctly, the formating will not look right and pictures will be red x. If you hit f5 to refresh the pages loads fine. If I add a deny any any eq 80 rule before the permit any any eq 80 the issue appears to go away. TAC can't seem to find anything worng. All we want to do is use a simple web content filter with the check boxes in the global filtering policy. ASA is running 8.2(5) and CSC is running 6.3.1172.0. Everything else works fine SVC and rules and such. [code]
View 2 Replies View RelatedWe use Cisco ASA 5520 (in HA configuration) connected to Cisco Switch 3750, ISP connection (25 Mbps) is straight to cisco 3750 switch. Since, Internet traffic is now high, a seecond ISP will be added.Our plan is to do Internet Link Load Balancing. My understanding that AS5520 can not do balancing.What appliance do you think I can use to accomplish the link balance?Also, take in consideration that our current ASA is also our VPN server and there are two DMZ zones.
View 1 Replies View RelatedWe want to achieve a load balancing scenario using Virtual IP on DMZ interface on a Cisco ASA 5520.
The IPs we are going to use on DMZ are 10.15.1.2 and 10.15.1.3
These IPs are going to be NATted to all inside IPs.
Lets say our outside IP is X.X.X.X
This IP points to 10.15.1.2 and 10.15.1.3 with .2 being the primary and .3 being the secondary. When I hit the outside IP, it should point me to .2 and that .2 should take me to the inside IPs.
This has to be the most weirdest issue I have seen since the past year on my ASA. I have an ASA 5540 running the 8.4(2) code without any issues until I stumbled upon this problem last week and I have spent sleepless nights with no resolution! So, take a deep breath and here is a brief description of my setup and the problem:
A Simple IPSEC tunnel between my ASA 5540 8.4(2) and a Juniper SSG 140 screen OS 6.3.0r9.0(route based VPN)
The tunnel comes up without any issues but the ASA refuses to encrypt the traffic but decrypts it with GLORY! below are some debug outputs, show outputs and a packet tracer output which also has an explanation of my WEIRD NAT issue:
My setup - ( I wont get into the tunnel encryption details as my tunnel negotiations are **** perfect and comes up right off the bat when the ASA is configured as answer only)
CISCO ASA - IPSec networking details
LOCAL NETWORK - 10.2.4.0/28
REMOTE NETWORK - 192.168.171.8/32
JUNIPER SSG 140 - IPSec networking details
PROXY ID: LOCAL NETWORK - 192.168.171.8/32
REMOTE NETWORK - 10.2.4.0/28
HOST NAME# sh cry ipsec sa peer <JUNIPER SSG PEER>
peer address: <JUNIPER SSG PEER>
[code]...
As you can see, there is no echo reply packet at all as the packet is not being encapsulated while it is being sent back. I have been going mad with this. Also, this is a live production multi tenant firewall with no issues at all apart from this ****** ip sec tunnel to a juniper!!
Also, the 192.168.10.0/24 is another IP Sec tunnel remote network to this 10.2.4.0/28 network and this IP SEC tunnel has a similar Juniper SSG 140 screen os 6.3.0r9.0 at the remote end and this woks like a charm without any issues, but the 171 is not being encrypted by the ASA at all.
We have an ASA5520 pair that we will be installing to load balance SSLVPN connections. Below is a portion of our configs pertaining to the VPN load-balancing feature (configured on both ASAs):My specific question is related to routing of return traffic to load-balanced VPN sessions. Is there some kind of persistence function that tells the return traffic which ASA to route back to? For instance, if ASA1 has a VPN connection having IP address 10.211.112.1 associated to it, and ASA2 has a VPN connection having IP address 10.211.112.100, how does the return traffic for each connection know which ASA to route back to?

View 7 Replies View RelatedA customer has an ASA5520 and 2 ISP routers with one WAN link each, and wants to split the load over both routers based on source IP ("natted" IP on ASA). I found this excellent doc on the topic: {URL}. Using PBR to achieve this is an option I was looking at, but I have come across a possible loop doing this with 2 routers. Setup:
-----------CE-1---------ISP-1
| |
| |
ASA55020---- HSRP |
| |
| |
-----------CE-2---------ISP-2
Both Routers receive default routes via BGP, and customer networks are propagated via BGP as well (i.e. the customer can specify the return path for the traffic). The ASA5520 forwards traffic to a HSRP virtual IP for redundancy purposes. If one router or ISP fails, all the traffic should use the other router/ISP. The customer wants to specify which traffic is sent over which link, by defining nat rules on the ASA. e.g. traffic sourced from the network 10.10.1.0/24 will always use ISP 1, and traffic sourced from the network 10.10.2.0/24 will always use ISP 2.
My problem: if I use route-maps on both routers (CE-1 and CE-2), sending part of the traffic to the other, and one ISP link fails, in my opinion I have a loop, since part of the traffic will get sent back to the router it came from. Is there any other was to achieve my goal without using PBR? I have looked at CEF and GLBP, but I cannot seem to find a way to load share via source IP.
Looking for a recommended code on the ASA 5585x firewall. We ran into a bug (CSCtr24705) on version 8.4.2 where it rebooted the primary firewall. The bug has to do with modifying an existing ACL that's part of a custom policy-map inside a service-policy. If we upgrade to 8.4.5 (which has the previous bug fix in it), there is another major bug (CSCud70273) where if you use the packet-tracer input command on an inside interface it causes problems too.
I don't understand why packet-tracer input would have a bug associated with it when it's been around for a long time and we use it on a daily basis for troubleshooting. Is there stable code for the 5585x to upgrade to without running into possibly a major bug? This is our core firewall so there are no VPN tunnels on it. It's setup in active/standby failover in routed mode.
1) 2 x ASA 5520, running 8.2
2) Both ASA are in same outside and inside interface broadcast domains – common Ethernet on interfaces
3) Both ASA are running single context but are active/standby failovers of each other. There are no more ASA’s in the equation. Just these 2. NOTE: this is not a Active/Active failover configuration. This is simply a 1-context active/standby configuration.
4) I want to share VPN load among two devices and retain active/standby failover functionality. Can I use VPN load balancing feature?
Active/Active failover is understood to mean only two ASA running multi-contexts. Context 1 is active on ASA1 Context 2 is active on ASA2. They are sharing failover information. Active/Active does not mean two independently configured ASA devices, which do not share failover communication, but do VPN load balancing. It is clear that this latter scenario will work and that both ASA are active, but they are not in the Active/Active configuration definition. Some people are calling VPN load balancing on two unique ASA’s “active/active”, but it is not
The other confusing thing I have seen is that VPN config guide for VPN load balancing mentions configuring separate IP address pools on the VPN devices, so that clients on ASA1 do not have IP address overlap with clients on ASA2. When you configure ip address pool on active ASA1, this gets replicated to standby ASA2. In other words, you cannot have two unique IP address pools on a ASA Active/Standby cluster. I guess I could draw addresses from external DHCP server, and then do some kind of routing. Perhaps this will work?
I have a customer who wants his new ASA-5520 to load balance out-going traffic between 2 ISPs, fairly normal request. Now here's the twist. He wants to separate traffic based upon the protocol used, http to one ISP, https to the other.

static (inside,outside) 10.21.197.0 10.17.197.0 netmask 255.255.255.0
our inside network is 10.17.197.X/24. the current NAT we have in place is 10.21.197.X/24.
we need to add an additional NAT of 10.22.197.X/24 and I also have networks that will need to hit the address with no NAT.
I do know the source networks where I need each of the three cases:
from 172.20.X.X I need to hit the inside of 10.17.197.X natively, no NAT.
from 192.168.X.X i need to hit the inside of 10.17.197.X with 10.21.197.X NAT

I also have McAfee Total Protection with a Home Network option to 'Trust' each PC to be able to connect them in a network within McAfee and scan each one for virus protection. That will not work either. It did once, but not now. All McAfee versions are up to date yet I see on some devices when they sometimes show up on McAfee that the program on the other computer is an older version. Then, when I do get the option to send a request to 'Trust' another PC, I'll enter a password to be re-entered in the other computer, then it'll instruct me to enter it into that other computer but then it fails before I can do so. It'll say the other computer is not available.

The EAP Methods I have tried on a SG-300-28P and ESW-540-24p switch are:EAP-TLS, EAP-FAST, PEAP Smart Card, I know that the radius server works because when I switch to a different switch the client works just fine, or if I keep the client on this switch and use any password method (PEAP (MSCHAPv2), MSCHAPv2, EAP-MD5) it also works. In both cases the radius server logged a EAP Timeout.

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 1 Replies View RelatedWe 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.
