Cisco VPN :: ASA 5510 Configuration Suggestion
Oct 31, 2011
we have a cisco ASA5510 and our client owns a Juniper device. we already have a vpn tunnel in place between the two locations and its working fine.Now, they have some networks which are in more secure zone, if we add those subnets to the present tunnel we are not able to access them. so what they are suggesting that we can reconfigure the VPN to be a route based VPN instead of policy based OR configure a second VPN tunnel.am not sure of cisco ASA supports route based tunnels???.. Can we create a 2nd tunnel between the same devices ( asa5510 and thei juniper device) as the IP remains same, only the internal remote networks will change for me. do i need to make any changes to the present tunnel??

I have attached a diagram of the current topology. At present, we have two 5508 connected to our core. We also have a 4402 behind the firewall (DMZ) just purely for guest access. So the staff users connect to the access point which in turns connects to the Staff WLC 1 (if this fails then to Staff WLC2). any guest user connect to the access point which in turn connects to Staff WLC which anchors to Guest WLC which then provides access. Since the guest is behind the DMZ they can only access the internet and not out internal network.
Now we want to office extend our network - we want our users to use 1132 AP at home to access the Infrastructure. is there a way we can do this without disturbing the existing infrastructure. On reading Cisco website, i know the best practice is to use 2 5508 (one behind the firewall and the other anchored to this access the internet network ) i thought since we have a Cisco (dmz) switch (48 port) and only the 4402 (Guest WLC) is connected to it, maybe purchase another 5508 WLC and connect to the 48 port Cisco (dmz) switch. will this work?

My router (D-LINK DIR-655) is in the living room under my TV in a cabinet with the lid closed (i would like to keep it that way, because the DIR-655 has the brightest led lights ever). My ground floor coverage is decent except in my back yard where i only get 1 bar or lose signal (we are talking about 10-15m distance). I am using mixed G & N mode with auto 20/40 MHz. In the past i had full bars in my back yard using a Linksys WRT54GL (Wireless-G) with DD-WRT firmware.
I have the following devices connected on my router: ISP MODEM / DREAMBOX / HTPC / DNS-325 / TV
1st Floor: I don't have any wireless coverage here, sometimes one bar but keeps dropping. This is where i would like to expand my wireless coverage in the whole floor.
2nd Floor: Here is my attic which i don't basically need any wireless. My main concern is in the 1st floor.

I am looking for a simple router recomendation for multihoming dual 100Mbps internet connections with BGP routing. What are the current best practices regarding required resources for the full Internet BGP routing table? We were thinking of specing a 3945 for this application, but is that overkill? The customer has a 2821 that is not in use, I'm thinking this would be too slow for Internet BGP routing combined with the 100Mbps line speed.

Current configuration:
2xASA5510s (Active/Standby) --->3925 Internet Router---->Internet
Going to:
2xASA5510s(Active/Standby)---->3925 Internet Router A----->ISP (Primary)
---->3925 Internet Router B----->ISP (Backup)
Note: Only one ISP just different speed connections
We're going to be using BGP to the ISP. Our goal is to advertise one subnet via BGP over both links using routerA as the primary and routerB only if it fails. How can should I configure my ASA and the internet routers to accomplish this?

I have a Cisco ASA 5510 connected to 2 private lans (1 for my HQ pc's{inside} and 1 for the worldwide mpls{outside}) It is also connected to the public internet at interface "public" and my dmz at "dmz" interface. I suspect I have a routing issue because packet-trace yields allow, the nat looks ok and the objects look ok at least to me but I'm the one with the non working config so...Basically this is the desired flow:
1. I need all traffic from the inside to be able to flow to the outside unimpeded as they are both trusted networks. (this is ok right now as I allow everything via access-list 101.)
2. I need any host on the public internet to be able to reach a server on the dmz via the pat which I set up from the "public" interface to the "DMZ" interface. The desired flow would be that the person on the internet types in [URL] and this is directed to the public interface ip which forwards to the webserver object on the dmz. (I cannot get this working any which way)
3. I need the dmz to be able to communicate with another server on the mpls via the "outside" interface when it recieves the request from the public it then checks with this other server on the outside via nat(translating the dmz range into the ip of the outside interface on the firewall)I have a default route that points to the mpls or outside interface for 0.0.0.0 0.0.0.0 via 10.x.x.1 - (and although I'm not sure I suspect this could be conflicting with traffic that needs to be sent to the "public" interface .... meaning that the firewall should dump packets bound for 0.0.0.0 0.0.0.0 to the public interface - 184.x.x.194 but I'm very reluctant to change the default route as this is in production and I'm not sure how it will affect traffic).However, I do suspect that if I changed the route from default to static as such:
route 10.0.0.0 255.0.0.0 10.x.x.1 (this would get all lan and mpls traffic to the mpls gateway) route 0.0.0.0 0.0.0.0 184.x.x.193 (this would send everything else from public to the public internet gateway)I think this is accurate but then I would bypassing my corporate internet proxy which is behind the mpls gateway at 10.x.x.1? Is there a way to get http traffic originating from the lan (10.x.x.x) to use the mpls gateway and http traffic for the dmz to use the public internet gateway at 184.x.x.193. I don't want to start causing a flow problem for the internet nor do I want to bypass my corp internet proxy.Either way I cannot get this to work, eventhough the logic checks out, I cannot get even a ping response when I allow icmp any any for testing. Note: I can ping resources on each network from the firewall, not only it's own ports in the associated network but other resources on those networks as well.
Here is the running-config:

I am attempting to set up FTP behind this new CISCO ASA 5510 we just bought. I haven't configured a cisco device in 5 years, so I am having issues., i think i am close. If I FTP from outside (fixed) IP it connects and takes the password but hangs on PASV and gives no data connection below is my configuration. It is simple since I seem to have the connection inside correct. and yes you can connect to the FTP server from inside without issue.

We have some users who use citrix outside corporate network through citrix web interface.These users are high priority users and we want to prioritize the citrix traffic. I want to make sure that my configuration will fullfill our requirements. Below is the configuration i was thinking to implement.:
ASA(config)# priority-queue outside
ASA(config-priority-queue)# exit
ASA(config)#access-list CTX-QoS extended permit tcp any 10.1.1.200
255.255.255.255 eq https

I am not seeing the IKE Policy configuration screens while configuring IPSEC VPN on ASA 5510. (Using ver 9.1(1) / ASDM 7.1) following the wizard after step 8, I am expecting the screen where you configure DES/3DES ,etc the screen does not show up - Have the right (3DES) licence.

BTW, the ASA is running version 7.0 (8) and I'm doing this through the command line.I've got a group of workers coming in a couple times per week that need wireless access to 1 printer on our network and internet access; I'll deny them access to the rest of our LAN.I've already configured an AP with WPA2 on a seperate subnet and put a router between it and our network. I've setup the router to apply an ACL to allow access to the printer's IP, deny to the rest of our main subnet, and permit everything else to go to our ASA 5510 that is serving as our gateway. From a laptop connected to the access point:I'm able to ping the printer's ipI'm not able to ping other workstations or our servers, as intendedI'm able to ping the ASA's inside interface The only part I can't seem to pull off is the final part of getting the ASA to translate the IP's from the new subnet to the outside interface.
So we have:
Laptop > Wireless AP > Router with ACL > Primary LAN > ASA5510 > internet
PAT is working fine for the primary LAN, but the laptop can't hit the internet.

I have been struggling to come up with the proper config to do a NAT of an incoming VPN tunnel to a VLAN on my network. I have an ASA 5510 with an IPSEC site-to-site tunnel to a partner network of 166.110.0.0/17.I have several VLANs on the ASA interface behind a cat4500 router (192.168.100.024, 172.16.4.0/24, 166.110.128.0/22 etc). The only network that the partner network sees is the 166.110.128.0/22.My problem is that I need to give them access to a node on my 192.168.100.0/24 net, but can't get the admin on the other side to add a route and adjust his tunnel.

creating a DMZ with my current configuration. Most of my configuration has been through the ASDM as I am still learning. I'm looking for a good tutorial through the ASDM to get me on my way. What I need to accomplish is this:
I have an internal GIS server which needs to have a constant database connection to an remote GIS Server which is already configured. I've got a separate VLAN setup on my 3750 switch which connects to the DMZ configured port on my ASA with a security level of 50. My GIS server has been placed in the DMZ VLAN which is accessible from my internal clients. I have a /30 Internet block which is being used for Internet and VPN. I have a separate /28 block that I'm assuming I'll need for the DMZ to work properly.

I've a problem with syslog logging on my Cisco ASA 5510 version 8.2(1). I need to:
- 1) log some ACL with warning level to log deny access.
- 2) log some ACL with informational level to log permit and deny access (notification level log only deny access and not permit access).
- 3) not log others ACL.
For 1), I configured the syslog server with warnings level and i enabled the logging rules with default level (syslog default level)
logging enable logging trap warnings logging host "interface" "host" . access-list "interface" extended permit ip any any log default.
For 2), I enabled the logging rules with specific level (informational).
access-list "interface" extended permit ip any any log 6 interval 300.
For 3), I disabled the logging rules.
access-list "interface" extended permit ip any any log disable
My problem is that the syslog logging level bypass the ACL logging level. Even if some ACL are configured with informational level, the ASA send only warnings logs to the syslog. I tried to configure the syslog default level to warnings, to remove the ACL and then put it back again with the specific logging level but I still have the problem.

I have Cisco 877-K9 router which sits behind an ASA 5510 FW. The Design :
Cisco 877-K9 DSL router (DSL with Static IP) ( DMVPN HUB )
||
ASA 5510 Firewall (Outside INT with Static IP / Inside INT LAN) (PAT & ACL)
||
Switch
||
LAN
Now my problem is, My Dmvpn configuration works just fine, I'm able to ping from my Cisco 877 to any Spoke & vise versa. I'm also able to Ping from my LAN to any Spoke Tunnel IP, but Im not able to ping any LAN IP at Spoke site nor am I able to ping my LAN from any Spoke site. I've googled alot but have come at designs where the ASA's are behind the Cisco Routers and not infront.

I have been working on my ASA 5510 version 8.2(1) trying to change the maximum connection time. Originally the custom "Group Policy" for IPSEC (Remote Access VPN) was set to inherit the settings from the default system Group Policy (DfltGrpPolicy). The custom group policy for the sake of this discussion is called "ABCD". I have modified the settings on the default (DfltGrpPolicy) as the custom policy (ABCD) was inheriting the configuration from default to disconnect after 1200 minutes. I changed the setting "maximum connection time" to 1200 minutes. I saved the configuration and what not then connected my VPN client, after two (2) hours I was disconnected. Something just doesn't add up.
I went ahead and deselected all inherited properties and manually configured them for the ABCD custom policy. No longer was the ABCD custom policy configured to use the inherited properties/settings. I saved the configuration again tested but instead of having a 1200 minute connection limit, I have 120 minute connection limit. Inside Monitoring --> VPN --> Sesssions : I can click on my session and see Session details". The Group Policy and Connection Profile properly list the "ABCD" custom profile. However, the "Conn Time Out" setting is: 120 minutes. I am completely stumped as to what is going on.
In the actual running config I see:
group-policy abcd attributes
banner none
wins-server value 123.123.123.123
dns-server value 123.123.123.123
dhcp-network-scope none
vpn-access-hours none
vpn-simultaneous-logins 3
vpn-idle-timeout 60
vpn-session-timeout 1200
What I need to do next to get this working short of a recycle of the ASA.

I'm trying to set up a new ASA 5510. I have a pretty simple set up with one /24 on the inside NATed to a DHCP address on the outside. Everything on the inside works and I can ping the outside interface from external devices. No matter what I do I can't get anything internal to route across the border to the outside and back. To try and eliminate ACL issues as a possibility I added permit any any rules to the incoming access lists on the inside and outside interfaces. Here's the sh run.

I currently have a LAN-based failover setup between two 5510s. The failover link is a crossover cable. In the current setup, if I unplug the crossover cable both units become active. From what I understood from Cisco documentation, each unit should mark the failover interface as down and there shouldn't be any failover. That's exactly how I want this setup to work.
