Cisco Firewall :: IOS Firewall Versus ASA (5505 / 5510) For Smaller Clients (less Than 50)?

Apr 24, 2012

We were having a discussion of ios firewall vs. asa for smaller clients(less than 50). On using ios firewall(zbf or cbac)and an asa 5505/5510.  One of the arguments brought up on using ios firewall on the router is that a router will do an ip sla failover.  I have configured a number of isr's for this and i know it works good.

Cisco Firewall :: Is Multicast Supported On ASA 5510 For IPSec VPN Clients

Dec 6, 2011

Our customer is using multicast in their internal network for their IP video deployemnt. Internallt on the network everything is working great.
 
We have two folks in management who want to be able to view the live multicast video feeds of the cameras remotely. I have tried to accomplish this using the Cisco VPN client. Although VPN connectivity is good (we can ping the individual cameras) they are unable to view the live multicast feeds. I enabled multicast globally on the ASA and the inside interface and get the same results.
 
Is there a way for the ASA to support the remote IPSec VPN client to view the multicast strams?

Cisco Firewall :: 5505 Remote VPN Clients Cannot Access Inside LAN

Apr 15, 2012

I have been asked to set up remote access VPN on an ASA 5505 that I previously had no invlovement with.  I have set it up the VPN using the wizard, they way I normally do, but the clients have no access to anything in the inside subnet, not even the inside interface IP address of the ASA.  Thay can ping each other.  The remote access policy below that I am working on is labeled VPNPHONE, address pool 172.16.20.1-10.  I do not need split tunneling to be enabled.  The active WAN interface is the one labeled outside_cable.

Cisco Firewall :: ASA 5505 / ACL To Allow Email Traffic Only To DHCP Clients?

Nov 14, 2011

So here's what I think I should do to give email access only to a segment of addresses of my inside network.
 
1) Create a network object for 62 machines that will represent my dhcp clients.I plan to use 192.168.0.65-192.168.0.126. So I will use address 192.168.0.64 with netmask 255.255.255.192. Then set DHCP server to service this address range.
 
2) Create an ACL which will Permit Any to use tcp port 110 (pop3) to get to the outside. Which leads me to question #1:
 
How do I permit the source "Any" to communicate with "Any Less Secure Networks" like the implicit rule that gets zapped once I create new ACL? Is "Any Less Secure Network" implied by the "Any" destination?
 
3) Create an ACL which will Deny my DHCP range to talk to the outside.
 
4) Create an ACL which will Permit Any to talk to Any Less Secure Network(essentially recreating the implicit Permit ACL that got zapped).

Cisco Firewall :: ASA 5505 Reach Local LAN And Internet From VPN Clients

I've enabled traffic on TCP 53-5000 port range according to Microsoft. My clients still can't join the domain. What ports I need to open up? My AD servers are Windows 2003.

Cisco Firewall :: ASA 5505 Not Giving Out DHCP To Clients / Only Discovery Packet?

May 3, 2012

My ASA 5505 has stopped giving out DHCP address to my machines.Everything was working fine and nothing has changed in the network. I've reloaded the firewall and clear all DHCP on the firewall I've even re-entered the cmd on the ASA.
 
I'm able to staticlly assigned address to the clients and all is way. When I do a DHCP debug on the ASA I don't see any events relating to the DHCP service apart from checking for lease expiry.
 
I've also tried to plug a machine straight into the ASA and no result. I finally did a packet capture and I am seeing the client machine sending out a DHCP discover packet and nothing else is responding.
 
My ASA config is:
 
dhcpd address 192.168.3.10-192.168.3.33 inside
dhcpd dns 8.8.4.4 interface inside
dhcpd option 3 ip 192.168.3.1 interface inside
dhcpd enable inside

Cisco Firewall :: 5505 Port Forward External Clients To 1 Address

May 4, 2011

I have a couple of ASA 5505's which work fine for what they are doing VPN and all that - we have 1 DLINK DFR-700 Firewall left and I need to get a new ASA to replace this since it is old.
 
All this box really does is port forward external clients to 1 address on the internal lan for client software updates. Any example configs?
 
So lets say we have client a with IP 1.1.1.1 and client b has 2.2.2.2 - at the moment this is what happens client a and b come in through http and get mapped to the internal http server 10.10.1.2
 
So I need to setup about 100 clients which can come in through http only - get mapped to the internal IP and also keeping the internal server to be able to access anything outside.

Cisco Firewall :: How To Configure ASA 5505 And 5510

Cisco Firewall :: ASA 5510 And 5505 Setup

Aug 16, 2010

I currently use MS ISA Server 2006 to protect a windows internal network, where there is also an MS Exchange server. I have acquired a Cisco 5510 to enhance security at main office. Later I will have ASA 5505 for branches, including VPN-ning. to have firewall at main office. I have several public IPs and would like to setup DMZ for Web, Exchange server and FTP. How do I setup interface and sub-interface for the DMZ?Can I continue using ISA Server connecting to Cisco 5510 on the perimeter? If so, How do I set the interfaces (and sub-interfaces) as well as NAT-ting and access configuration between the inside and outside?

Cisco Firewall :: ASA-5510 / ASA-5505 Loses Connection To Gateway

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.

Cisco Firewall :: ASA5520 Individual Ports Versus Ranges

May 27, 2013

Best practices for an ASA5520. I'm currently running a pair of these as internal firewall for my organization, and have about 750 rules dictating traffic. A lot of the rules are for individual ports to specific server(s), some of them having 50+ ports opened. For example, Exchange has about 115 ports opened right now, anywhere from port 25 to 55000.
 
My question is that would it be better (faster, less strain on the ASA) to open a port range, (ie 52000-55000) or would the individual ports (ie: 52112, 52336, 52698,53441,53495, etc...) be ok?Obviously the individual ports are much more granular for security, but I don't want to take that into consideration now. Just strictly individual ports vs ranges.

Cisco Firewall :: ASA5505 DMZ Configuration Versus Linksys E4200 DMZ

May 11, 2013

I am using a Cisco E4200 router today but I am moving to a ASA5505.   I have a device that sets up a VPN tunnel that I want to put in my DMZ.   It's called the ATT Gateway.  I have attached the diagram.   When I use a Cisco E4200 all I do is put the outside private ip address of 192.168.0.99 of the ATT Gateway into the DMZ of the E4200 and the VPN tunnel of the ATT Gateway comes right up. I cannot configure the DMZ to do the same with the ASA.   I also need to have the laptop behind the gateway access the printers in the inside network.

Cisco Firewall :: 5512 - BGP Through ASA Versus Transparent Mode Deployment

Mar 8, 2013

I've been asked to deploy an ASA in Transparent Mode because of concerns of putting another layer 3 hop between PE and CE routers running BGP.
 
Is there some problem with allowing BGP to flow freely through an ASA the is also terminating site to site and remote access vpn tunnels?
 
I just don't see the need for Transparent Mode here and you cannot have a standard DMZ setup with Transparent Mode: you have to use bridge groups to provide for multiple interfaces on the ASA and then have an external router route between those bridge groups.
 
what I'm missing here as to why Transparent Mode is needed (not needed)

ASA is 5512

Cisco Firewall :: Site-to-Site VPN Between ASA 5510 And 5505 Configuration

Apr 18, 2013

I am not very experienced with Cisco networking.

Here is the situation.
 
Site A - headquarters 192.168.1.x
Site B - remote office 192.168.20.x
Site C - remote office 192.168.30.x
 
Site A - ASA 5510
Site B - ASA 5505
Site C - ASA 5505
 
Site-to-site VPN is established and works between A and B, A and C. Users would like to establish a tunnel between B and C to work on a common project and the data is on Site B.
 
I tried configuring the S2S VPN with pre-shared keys on both firewalls at sites B and C but in the end it is not established (I cannot ping either side). I used the Wizard interface multiple times and one time the CLI. I generally followed the settings chosen between the headquarter and the individual remote sites and tried to replicate them. Obviously I have made a mistake somewhere.
 
Could there be any limitation on the ASA 5505 in terms of licensing and the number of S2S tunnels?
