Cisco Firewall :: ASA 5505 Supporting Concurrent Multiple ISP For Anyconnect VPN
Aug 13, 2012
Our current cable ISP is having issues providing us with consistant connectivity. I would like to bring in a second ISP to allow my users to choose where they will connect to. There will be two dns names and i just want to to be able to choose between them.
Is this possible on the ASA5505? supporting two ISPs at one time for VPN on both?

What anyconnect version do I need on a 5505 so i can have people connect via iOS devices? Right now I have "anyconnect-macosx-i386-2.5.1025-k9.pkg" on there, will that work for iOS devices?

I have a ASA5505 with the Sec Plus license on it. This allows 25 VPN peers at any time according to the show version output:
Licensed features for this platform:
Maximum Physical Interfaces : 8
VLANs : 20, DMZ Unrestricted
Inside Hosts : Unlimited
Failover : Active/Standby
VPN-DES : Enabled
VPN-3DES-AES : Enabled
VPN Peers : 25
WebVPN Peers : 2
Dual ISPs : Enabled
VLAN Trunk Ports : 8
AnyConnect for Mobile : Disabled
AnyConnect for Linksys phone : Disabled
Advanced Endpoint Assessment : Disabled
UC Proxy Sessions : 2
This platform has an ASA 5505 Security Plus license.
1.)As far as I understand this means RA users and peer2peer combined?
2.)I need additional RA clients to be able to connect in at any time, as far as I know there is no way to allow more IPSEC clients then this due to hardware limitations?
3.)If I go for the Anyconnect option (10 users license), does this then mean that I can use the 25 IPSEC VPNs and at the same time have users using the 10 SSL Anyconnect VPNs at the same time?
4.)Which Anyconnect license am I supposed to buy if this is the route I go, the clients will all be connecting from their desktops most of the time?
5.)Is it difficult to set up?

A customer has a 5505. According to the datasheet the limit of IPSEC sessions is 25 and the limit of anyconnect sessions is 25. Does that mean I can have 25 IPSEC tunnels and 25 Anyconnect tunnels at the same time? The customer needs at least 50 concurrent tunnels on his ASA. Am I understanding it correctly?
I was thinking the customer could pay for the anyconnect essentials license and connect his anyconnect clients to the ASA. Is that a good option to get the 50 concurrent clients connected?

I'm trying to configure an ASA 5505 to view my Slingbox from my iPhone/iPad from an outside or 3G network. I can't ping my internal networks while connected via AnyConnect. I know that I need to free up port 5001, but I can't seem to get it to work.

I have a base 5505 and would like to get AnyConnect working. To do that, would I have to first purchase either an essentials or premium license and then purchase the AnyConnect Mobile license?

I have an ASA 5505 that I log into and currently only need a password to log onto the device. How do I set it up so a username is required as well?Another user needs to access the device. How would I set that up so they have to user their own credentials? I tried username apssword priv command and it does not work.

We have a working config with 1 external IP, we need to a second webserver (https) and it should be routed via a second public IP address. I already tried some suggestions from the community but haven't been able to find the solutions.
xxx.xxx.xxx.194 is going to the internal IP of 192.168.60.1 for OWA (https)
xxx.xxx.xxx.195 should go to a new webserver on 192.168.60.3
both server should be connected using SSL This is the current configuration :

Attached is my updated ASA 5505 (8.4[2]) config. With this config, basically the "laptop" group works fine, but the leo and orion groups don't ever receive packets inbound. No DNS, nothing.
The laptop is windows, the other two are servers with two NICs. The interface cards are Intel Pro/1000s. I've been through everything including Vlan protocol conflicts and actually enabled the servers for 802.1(Q).

I have 3 networks coming on DMZ (VPN) interface. Only one network is able to ping the DMZ interface. See below networks coming i on the DMZ.
10.132.24.0/2410.132.25.0/2410.132.26.0/24 Only the 10.132.26.0/24 netork works as it is in the same range as the DMZ interface.
allowing the other two networks to communicate. I've attched the diagram and configs for your perusal.

I have a problem with a ASA 5505. He is crashing multiple times during the day. I've setup a syslog server en I'd noticed that the last two log notification were:

It's a 5505 with a 10 user inside host license, wich incidentally is more.

We currently have 2 different ASA 5505 connect to our ASA5510. We want to VPN connect the 2 5505's to each other while still mantaining connection to our 5520. I have attached pdf of what we have. What we want is to connect traffic between the two 5505's so that devices in either location can talk to each other while still mantainig connection to the 5510.

I want to know with an ASA 5505 w/ Security Plus License I get up to 20 VLANS/Named Interfaces.I have a customer that is getting a new subnet of external IP addresses from their service provider and a different default gateway to accomodate re-hosting their datacenter at their main office instead of at a Colo. My question, when building out their new DMZ, can I have multiple route 0.0.0.0 commands?
Example.
Current Default Gateway 1.1.1.X
Internal hosts 192.168.1.0 use and are natted to 1.1.1.X
New Default Gateway for DMZ Servers 2.2.2.x
Internal hosts still use 1.1.1.X, but server hosts in 192.168.1.3 should use 2.2.2.X -- there are also a bunch of pre-existing static NAT rules for these servers such as 2.2.2.30 translates to 192.168.1.30.
I think I would accomplish this by using the following:
route inside 0.0.0.0 0.0.0.0 1.1.1.X
route DMZ 0.0.0.0 0.0.0.0 2.2.2.x
Would this be correct?

I am setting up a Cisco ASA 5505 first time for My organisation, I usually setup Cisco Router, I have 10 Static IP, & Have 6 Server (S-1, S-2, S-3, S-4, S-5, S-6), Traffic Should be pass through the ASA and is distributed to the destination server that is specified in the packet. LAN servers can be separated into discrete networks for security. For example, a private LAN for internal traffic accessed only via remote dial-in VPN sessions and Want to Configure DMZ for Server (S-4, S-5, S-6) that allows public web traffic.
I have Attached My Network Diagram I have some question,
1:- Can we Configure Multiple Static IP On ASA 5505 ?
2:- If Diagram is wrong what change need to be done ?

We've read everything about inspecting SIP packets and allowing them to pass through on port 5060, the default SIP port. However, our setup requires the ASA 5505 to allow SIP on ports 5060, 5160 and 5260.
Is this possible with the ASA 5505? If it's not, it would be a blocking issue for us to move forward with ASA appliances. We are currently investigating in a lab environment and really having difficulties configuring it to facilitate full SIP functionality.

I have an ASA 5505 running 8.2(1), that is configured with three interfaces as follows:
Inside (security 100) 10.0.0.0 /24
Inside 2 (security 100) 192.168.0.0 /24
Outside (security 0) internet
Inside is connected to my internal network, inside 2 is connected to the network of a sister organization, outside is outside.
I'd like to be able to route between from inside to inside 2, and have NAT translate me to inside2's address.
I have inter-interface traffic configured, and when I use a NAT exemption, I can route fine. But the resources on network 2 must see my request as coming from the inside2 interface IP.

This is for an ASA 5505 with the base license...I have a situation where I will not have one interface in my outside VLAN, but instead I want to have interfaces 1-7 in my outside VLAN and interface0/0 in my inside VLAN.
Is this supported with the Base license, and if so how would I do this? Do I still just need to assign one IP address to the outside VLAN?
Or will I need to upgrade to the Security Plus license and put each interface in a separate outside VLAN, so in essence I would have 7 outside VLANs each with the same security level (0)?
My situation is that I have several partner networks that i want to "aggregate" thru my one ASA 5505. So each outside interface represents a separate partner (outside) network, each of which I want to get to from my inside network. Hence the many outside to one inside.

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.

I have an ASA 5505 with the security plus software and I'm trying to find out how to assign 2 public IPs to the outside interface and have each IP routed to a separate internal VLAN. For example, IP 1 = X.X.X.1 routed to 192.168.1.0 and IP 2 X.X.X.2 routed to 192.168.2.0. I was told this was possible and I've been trying to find configuration examples, but I can't seem to get anywhere and now I'm getting desperate because I'm scheduled to install it this weekend.

I'm stuck at asa 5505 nat, port forwarding configuration Here is what i need:
host1: 192.168.1.1 service tcp/100 >>>>> public ip 1.1.1.1 service tcp/100
host2: 192.168.1.2 service tcp/200 >>>>> public ip 1.1.1.1 service tcp/200
host3: 192.168.1.3 service tcp/300 >>>>> public ip 1.1.1.1 service tcp/300
So people from remote just need to use 1.1.1.1 public ip to access all the ports on three different inside server.I can do this on my old ASA 5505 with 8.0(4). Looks like there're lots of change from 8.0 to 8.4.

in Cisco ASA 5540 Adaptive Security Appliance Platform Capabilities and Capacities, I see Concurrent Sessions: 400,000. Which mean what device can handle 400,000 session and no more. But if I'm using TCP State Bypass Feature (Inbound traffic pass via ASA but Outbound goes via different device). I can see such connections via show conn command with b flag.
My questions: 1. Will this limit (Concurrent Session) affect in this case? Or ASA can handle more such connections (for example 800,000 ...) in bypass state? 2. It's possible to tune timeout for such connection without using global timeout conn? My problem what I want to do by pass tcp connection for one IP with has very high connection/sec rate.

I use a Cisco ASA 5510 with the AnyConnect VPN for remote workers. Now we want to give access to a select group of consultants who only need access to one sever and block everything else.
I was thinking this could be done by creating a separate AnyConnect Connection Profile on the ASA. From that new connection will come a new GroupPolicy with a ACL to only allow access to the one system. That GroupPolicy will point to the Radius Server looking for an account in a specific MemberOf group.
My question is - Could you explain how the ASA knows what Connection Profile to use when a user tries to authenticate? Does it automatically hunt down each Connection Profile until there is a username match via RADIUS in the Connect Profile?
