Cisco Firewall :: ASA 5510 With Two Outside Interfaces Which Is In Separate ISPs
Jan 5, 2013
I have ASA5510 with PLUSE License.I have 2 Inside interfaces as STAFF and MAIL and two Outside interface OUT_STAFF and OUT_MAIL which is in separate ISP's.now i want to nat STAFF to OUT_STAFF and MAIL to OUT_MAILbecause I'm having two default routes it gets impossible to do.
Due to special circumstances we have 2 ISP links on an ASA5510. I am trying to terminate some L2L VPN tunnels on one link and others on the second ISP Link, eg below:
LOCAL FIREWALL crypto map outside-map_isp1 20 match address VPN_ACL_Acrypto map outside-map_isp1 20 set peer 184.108.40.206crypto map outside-map_isp1 20 set transform-set TS-Generic crypto map outside-map_isp2 30 match address VPN_ACL_Bcrypto map outside-map_isp2 30 set peer 220.127.116.11crypto map outside-map_isp2 30 set transform-set TS-Generic crypto map outside-map-isp1 interface ISP_1crypto map outside-map-isp2 interface ISP_2 crypto isakmp enable ISP_1crypto isakmp enable ISP_2 route ISP_1 0.0.0.0 0.0.0.0 18.104.22.168route ISP_2 22.214.171.124 255.255.255.255 126.96.36.199
Establising the VPN tunnels in either direction when using ISP_1 works fine establishing in either direction from remote access users and multiple L2L tunnels (only showing one for example).
On ISP_2 1. Peer 188.8.131.52 device establishes a VPN tunnel, but the return traffic does NOT get back to devices on 184.108.40.206 tunnel. 2. The local firewall does NOT establish a VPN tunnel going to 220.127.116.11 It would seem to indicate that the problems lies with this multihomed firewall not directing the traffic correctly to either return down and establised VPN tunnel (point1) or to intiate a tunnel if none exists (point 2).
Reconfiguring the VPN tunnel peer for 18.104.22.168 to be on ISP_1 of the local firewall, all springs into life! There are sufficient license etc...
Currently we have a T1 for data connected to a 1721 Router that is connected to an ASA 5510. We would like to add a FIOS line for dedicated online backup. Is it possible to connect the FIOS router to the ASA and route the IP from our backup server to use the FIOS line and everyone else continue to use the T1?
What we are trying to accomplish here use two ISP's (one cable and one T1), use the Cable line for site-to-site VPN and use T1 line for all internet traffic. We currently use the following configuration: Cisco 2820 routers terminating the T1 -> HP switch -> Cisco AS 5510 port 0 -> port 1 to LAN switch (Nortel 5510)We want to force all VPN traffic (using 10.0.0.0/24 subnets - 10.0.1.0, 10.0.2.0, etc) through a cable connection, perhaps on port 2 of the ASA, then all non VPN traffic goes to the T1.
I am in the process of configuring a ASA 5510 to replace an older PIX. This change is part of migrating to a new ISP, so the process is complicated by the existence of two outside interfaces. I have virtually everything working, but there is a requirement to be able to access hosts from the internal networks using both their private IPs and their public IPs. The older PIX took care of this silently with little configuration, but the ASA has me twisted on the details. Some of the hosts with public IPs are on the internal network and some are on a DMZ (not my design, inherited). For the internal ones I implemented hairpinning to take care of the requirement, but I am having trouble with the DMZ based hosts.. Since there are two external interfaces each internal host has two IPs and two static NAT rules to handle incoming traffic from each external interface.
The routins and dynamic NAT entries we have in place take care of accessing the hosts using their private IPs on the DMZ, but I cannot figure out how to get the public IPs to work from the internal network. It seems like a simple Static D-Nat shoudl do it, but when I add a Static D-Nat on the DMZ the public IP works, but the private IP breaks.. Is there a way to get them both to operate ?
Network layout looks like this (IP ranges altered):
DMZ 22.214.171.124.0 Class C INTERNAL 10.0.0.0 Class C Outside 126.96.36.199 Class C Outside2 188.8.131.52 Class C
After applying it I could access the public IP (184.108.40.206) from the internal network, but I could no longer access the DMZ IP (220.127.116.11) from the internal network. Is there any way to get this configuration to allow access to both IPs from the internal network ?
The problem here is that there are website links based on the public IP and the DNS is split so DNS returns the internal IP to users. As a result both need to be accessible from the internal network.. Not my favorite design, but the client (or in this case the boss) is always right so I need to get it working somehow.
The Voip pbx resides on a seperate lan, not connected to the ASA. Users from behind the ASA (inside) try to connect to the VOIP pbx using a soft phone. The Voip connection is established, however users cannot here conversations on either end.Im assuming this is possibly a Sip and Pat issue? The ASA firewall is using a seperate Global IP for PAT. Also I have opened ports on the outside interface for SIP udp 8081, 2088,16000-16010 and 15000-15511. I have both SIP and H323 h225 inspection in place as well.
We have an ASA 5510 and we also have two separate address pools which have been provided by our ISP. The addresses are not contiguous. Is there a way to configure an interface on the ASA to handle both sets of public address pools? If the outside interface is set up on eth0/0 would I create two subinterfaces (eth0/0.1, eth0/0.2) and assign each subinterface an address pool? Then just NAT/PAT to my heart's content? At that point I would want both to route to our inside network. So it's basically two inbound sets of IP addresses comming into one interface and then comming into the network... Right now the outside interface is configured with our first set of IP addresses. We wanted additional addresses and when we called our ISP they told us we already had them - just a different pool. Hence the question. I'm guessing that I wouldn't put anything specific on the outside interface and I would put the specifics on the subinterfaces?
I've been following most of the comments in regarding how to allow communication between two internal networks on a ASA5510 8.2.5 But I am still a little confused about to how to set my firewall. I made chages to it and still do not have the desired results.
I need to allow comunication between Interface 0/1 and Interface 0/2. See configuration file with fake or dummy ip address below.

I have a question regarding firewall configurations. Is it possible to have two interfaces ( for two internet service providers) one for voice and one for data. Can I have two Outside Interfaces that one will apply to a pppoe client group and the other will apply to a static IP? Is this possible and if so What would be the steps on applying this connection? Also to note I have a point to point connection already established for the pppoe. I also have another point to point connection for data, but however I do not know how to apply this to the firewall.
I am trying to setup intervlan routing with a Cisco ASA 5510 and two 2960-S switches. The 5510 currently is using ASA Version 7.0(2) and has a base license. I tried to create a sub interface today based on some info I found regarding the routing piece and it didn't recognize the command. I'm thinking I may need to update the IOS code or the license on the firewall. I know the syntax was correct because I looked it up and found it in a Cisco document.
we have two ASA 5510 connected in failover, and a pair of cisco 2960s switch connected in stack. Currently one interface of primary ASA is terminated on switch1 and a interface from standby is connected to switch2 as Inside, and switch1 and switch2 are in stack. for redundancy purpose i want to use multiple interfaces of ASA for inside , so first i thought to use etherchannel , but it has a limitation that , it cannot be terminated on stack switch(as per cisco document [URL]
So my question is :
1. can we use redundant interface feature where 2 physical interfaces combined to a redundant interface (eg interface redundant 1) for inside redundancy purpose.
2. Can these ports from primary/standby ASA terminated on stack switches (2960s), will this work (if the switch with active port goes down, will the other port take over in the redundant interface with the other switch).
I have a Cisco ASA 5510 with 3 inside interfaces each connected to a 3750X switch port in a vlan. Outside interface is connected to external router with 209.155.x.x public IP. Static route exists for outbound traffic on outside interface.
3750X is configured for inter-vlan routing. VLANs 10, 20, and 30 have 172.16.x.1 IP address with static routes pointing to the each of the ASA inside interfaces - 172.16.x.254. Connected hosts are configured with gateways pointing to the appropriate vlan interface IP - 172.16.x.1.
Inter-vlan routing appears to be working - I can ping back and forth between hosts on different vlans, and I can ping each vlan IP.I can also ping each ASA inside interface from a host in the appropriate vlan, but I cannot ping internet sites (18.104.22.168 or 22.214.171.124) from hosts on the inside interfaces.
I can ping 126.96.36.199 from the ASA CLI. I can ping internal hosts on vlans 10,20,30 from the ASA CLI. But, no luck with pinging from inside host to internet hosts
I have a 2811 Router with two fast ethernet wic cards installed. I need traffic to go out one interface, but it's received back through another. Both interfaces have public IP's and the same subnet, and are connected directly to satellite modems. One can receive data / the other only send.
I am having a strange requirement. actually I am not sure it is strange or not. I am having ASA5510 with 8.4 sw version. Currently one ISP is connected to it. It is working fine. We have some servers that are directly connected to internet using another ISP connection. These servers having public IP addresses configured on their LAN settings. I need to move these servers in to the DMZ zone.
When i connect it to the ASA's DMZ zone,servers will get internet through the first ISP that is already configured on ASA. But i need to NAT the DMZ servers with the IP address provided by the other ISP, which even not configured on ASA.
So what should i do? In short my requirement is
1) need to NAT the server with the IP address provided by another ISP
2) Also note that the default route is configured for the first ISP only in ASA
so Do i need to configure another default route? Do i need to make it with larger AD? So i do it will act as the secondary route only.
I need to make the ASA up and running for two ISP, and servers in the LAN should be able to NAT with the IPs of first ISP and ,the servers in the DMZ zone should be able to NAT with the public IP of the new ISP.
We have plans for multiple ISPs and need to pick the correct device/architecture for that. single site: 3 ethernet hand offs (1 From ATT Fiber/10Mb pipe via their managed router, another one from ATT via Copper T1 via a separate circuit & managed router and the 3rd/last from Cable Modem/Comcast)
1.WAN hand off from another ISP from I will use ASA 5510 (already have) to use all the above 4 as inputs and then use the internal interface of the ASA 5510 as the default gateway for all the employees to browse the internet etc. so that1. If one one or more of the ISP lines die, we continue to operate (albeit lower bandwidth)
2. Also, we take advantage of the added bandwidth (even though it may not be the arithmetic sum of all the above).
I need to know how to setup my ASA with dual wan links. 1 is 10/10 fiber, other will be a 50/5 Cable Wideband link. The 10/10 fiber is currnetly being used for VPN's and Internet, (about 20 point to point IPSEC vpn's currently).
I want to add the Wideband link and use the "Tunneled (Default gateway for VPN traffic)", feature for the current fiber link and the new Wideband link for any other internet traffice. I tried this however as soon as I set my fiber link to "Tunneled (Default gateway for VPN traffic), I lost all connectivity.
I also setup my "VPN" link with the "tunneled" option and my "INTERNET" link with a default route to the internet. This would only let me ping internet sites from the ASA device but not from client computers, also the VPN's would not come backup.
I have tried the sla setting with a DSL line for failover and that works good, i've since got rid of the DSL and want to utilize 2 wan links for different purposes/traffic.

is it possible to have the ASA connected to two ISP's and use the one ISP connection for Client/S2S VPN and Internet Access and the second ISP connection just for the WebVPN Traffic? How would you manage the Routing, as the default route is pointing to the first connection or is that not an issue here?
I'm setting up two separate 5510's at two seperate locations. The client wants two seperate SSL-VPN's; one for the HQ and one for the COLO location. They have a single domain for which I have added a-records to point to the corrosponding ASA's thusly: [code]
My questions is this: do i need to buy seperate certificates for each ASA/fqdn/IP combo? I'm using godaddy to buy the certs. If I do need to buy seperate certs, that makes the installation easier, but may waste $$. If I only need to buy one cert, how do I set it up so that both combo's are verified?
We are starting to deploy SSL VPN in our company and we recently purchased two ASA 5510 firewalls. I have already completed the initial configuration but I do have some inquiry on how to have it configured properly.
1. Employees and clients will access the URL 2. They will select the appropriate group on where they should login. 3. Enter credentials, etc. 4. Username/Password authentication is via RADIUS. The usernames were all created in Cisco ACS 5.3.
My challenge is, we have several clients and all their usernames were created in ACS5.3. Meaning if the configuration is just being differentiated by group settings, clientA can select the profile of clientB and still get authenticated. If that happens, they will be able to access the resources of each other. Also in the future, we will be deploying 2-Factor authentication for some of our clients.
Looking to replace an "all-in-one" type firewall (UTM/Firewall, SSL VPN) with a cisco product - the issue i'm running into is that we have multiple ISPs plus WAN and DMZ - overall more than 5 ports on mid-range ASA devices - and from what i read, adding 4-port module precludes me from adding CSC module.
Is there an solution to that other than going for 5585-x model? (kind of over our budget, granted we need 2 for failover)
Site A has an ASA 5510 and a single internet connection.Site B has two internet connections (primary and backup). If Site B also has an ASA, I can configure Site A's ASA to deal with a failover at Site B (set peer 188.8.131.52 184.108.40.206). Does this work if Site B has an IOS router instead of an ASA? In other words will "set peer 220.127.116.11 18.104.22.168" on the ASA work when it's talking to IOS on the other end?
I have a Cisco ASA 5510 and I am trying to set it up to be able to have it failover to the 2nd ISP connection if the 1st one ever went down. I think I need a nat statement that the "backup" connection will use when the 1st connection goes down, but I am unsure what the nat statement is supposed to be. I have added the commands that I am pretty sure that I need to add for the "backup" ISP connection. Attached are those commands, the interfaces that are set up, and the objects that are set up in the ASA.
I inherited a network redesign project mid implementation and ran across an issue that I was not 100% sure able to be resolved. Implementation is occurring in which the organization is changing over to a different ISP and we have some customers that will not be able to change their settings over to our new addresses from some time. I have seen a lot of posts about fail over and dual ISP configurations, but I could not relate them to this particular scenario.
have a PIC 515e connected to two ISPs via 2 interfaces. ISP1 is a 3.5Mbps aDSL line, and ISP2 is a 30Mbps business cable. I've confirmed the speeds by connecting the cabled directly into a laptop and using wget to download very large files from known-fast sites.
For admin reasons, I need to access two specific subnets using the slower ISP1. The rest of internet traffic should go to the much faster ISP2.
So I configure ISP2 as the default gateway, static routes for the two subnets to ISP1, set up NAT (PAT) and it all works like a charm. I've confirmed that ISP1 is used for only the two subnets, and ISP2 for everything else. CAPTUREs on the pix also confirm this. So far, it all works great.
But for reasons I don't understand, my max. download speed is 3.5 Mbps (the slow DSL). Using various speed tests and wget, I simply cannot get a download speed faster than my 3.5 Mbps DSL line.

I have to configure failover Active/Standby on my ASA 5510.I am wondering how i could do for the outside interface, i mean, actually the ASA1 outside interface is linked directly to our Internet router.So now if i have to add ASA2 connecting to that router i will need a switch between them.I have already a switch for DMZ & LAN.The thing is that i will have to allow 3 switchs ports to communicate with each others.
- 1 for ASA1--outside - 1 for ASA2--outside - 1 for Internet router
How could i isolate these 3 ports to make them communicate alone ? Should i use VLAN for that ?And if i use VLAN, will this require to make any change of configuration on my firewalls (ASA1 & ASA2) outside interface ?I am a bit lost with this, if i am correct i will not have to do some "vlan tagging" on the firewall itself ?
