Question

Site-to-Site VPN from ASA 5505 to PIX 501 with Client VPN on ASA 5505

Asked by: RishMaster

I'm trying to get a site-to-site VPN going between a Cisco ASA 5505 and PIX 501. The ASA 5505 currently supports client VPN and I want to keep that.

I'm guessing my issue is that the PIX 501 is on the same subnet as the client VPN pool, but I'm not sure.

I've posted my ASA and PIX configs below. Please let me know how to correct this and any other things missing/incorrect in my configs.

On a side note, can the Cisco VPN Client 4.8 support AES VPN?

>>I'm guessing my issue is that the PIX 501 is on the same subnet as the client VPN pool, but I'm not sure.

Yes, that is a problem. I would change the VPN client pool to a different network range, say 10.10.1.0/24 or something other than 10.1.1.0/24 or 10.1.2.0/24.

>>On a side note, can the Cisco VPN Client 4.8 support AES VPN?

No, but I haven't seen any documentation saying that...I only have anecdotal evidence to support that answer.

by: RishMasterPosted on 2008-01-02 at 16:52:51ID: 20569589

I have moved it to 10.1.5.0/24 and the VPN still works but the site-to-site doesn't.

Hi Rishmaster
I dont see cryptomap entries for site-to-site?

crypto map outside_map 20 set peer 209.89.45.8
crypto map outside_map 20 match address outside_cryptomap_20

Regards

by: RishMasterPosted on 2008-01-03 at 10:19:03ID: 20575084

I think I already put those in but it doesn't display in the running-config.

When I add "crypto map outside_map 20 set peer 209.89.45.8" it says "ERROR: Multiple Peers can be specified only with originate-only connections".

"crypto map outside_map 20 match address outside_cryptomap_20" takes fine.

by: RishMasterPosted on 2008-01-03 at 10:48:00ID: 20575332

OK, so I seperated the site-to-site crypto's/isakmp from the VPN crypto's/isakmp. The site-to-site doesn't work but at least I can add those lines in properly.

I've attached the updated ASA and PIX configs.

I would try using group 2 for DH on the tunnel:

PIX:

no isakmp policy 20 group 5
isakmp policy 20 group 2

ASA:

crypto isakmp policy 20
group 2

See if that helps...

by: RishMasterPosted on 2008-01-03 at 12:30:46ID: 20576362

Hi batry_boy,

Thanks for your suggestions. I changed from group 5 to group 2 but still no luck.

BTW, is there a quicker way to refresh the ASA / PIX without doing reloads on both sides?

by: batry_boyPosted on 2008-01-03 at 15:38:56ID: 20578259

Since you only have one site-to-site VPN tunnel configured, meaning you won't affect any other tunnels if you do this, you can issue the commands:

clear crypto ip sa
clear crypto is sa

And then try to send interesting traffic to bring the tunnel up, such as pinging a host on the other side of the tunnel. Before you do this, turn on debugs so that we can see how far the tunnel setup is getting, if anywhere at all:

debug crypto ipsec
debug crypto isakmp

Post the output of those commands.

by: RishMasterPosted on 2008-01-03 at 15:50:45ID: 20578340

When I run "sh crypto is sa" and "sh crypto ip sa" on both devices neither of them indicates there's a tunnel.

by: batry_boyPosted on 2008-01-03 at 15:55:45ID: 20578379

Yes, I know...did you perform the "clear" commands I posted above? When you asked about the quickest way to "refresh" the firewalls, I thought you meant in regards to the VPN tunnel setup. Since establishing the VPN tunnel in the first place is your issue, you won't see any output from the "sh cryp is sa" and "sh cryp ip sa" commands.

But if you enter the debug commands above, you should see the tunnel trying to be negotiated as long as interesting traffic is being sent that causes the firewall to try and bring it up.

by: RishMasterPosted on 2008-01-03 at 16:10:07ID: 20578488

Sorry, I was trying to explain that nothing was appearing after I put in the debug commands. So I ran the "sh crypto is sa" and "sh crypto ip sa" commands...

I pinged the PIX from the Server behind the ASA. Below is the debug dump from the PIX. Nothing appears on the ASA.

I ran "debug crypto ipsec 127" and "debug crypto isakmp 127" on the ASA and here's the output when I pinged from the server behind the ASA to the PIX local IP.

From line 203 of your code posted above, it looks like Phase 2 is completing which means that your tunnel should be up. Still no output from the "sh cryp is sa" or "sh cryp ip sa" commands?

by: RishMasterPosted on 2008-01-10 at 13:40:00ID: 20631570

AF-SHE-FW-01# sh cryp is sa

There are no isakmp sas
AF-SHE-FW-01# sh cryp ip sa

There are no ipsec sas

by: batry_boyPosted on 2008-01-13 at 20:49:20ID: 20650976

I noticed that the hostname of the firewall you issued the "sh cryp" commands on above is different from the "ASA" hostname on your ASA...did you perform this command on the PIX? If so, what do you see when you issue these commands on the ASA? The reason I'm asking is because the debug output you posted is from the ASA which looks like the tunnel is being established.

by: RishMasterPosted on 2008-01-14 at 12:03:35ID: 20656171

Sorry, I renamed my ASA to AF-SHE-FW-01 and the PIX to AF-LED-FW-01...

by: batry_boyPosted on 2008-01-14 at 12:46:21ID: 20656576

Try adding an additional isakmp policy on the PIX specifying DH group 2 and 3DES...I've never used group 5 with a PIX before, it may be causing problems. Also, if you get 3DES to work, then maybe later you can try it with AES, but for now let's just see if we can get the tunnel to come up at all. You need to add the following commands to the PIX...the ASA already has equivalent statements:

isakmp policy 10 authentication pre-share
isakmp policy 10 encryption 3des
isakmp policy 10 hash sha
isakmp policy 10 group 2
isakmp policy 10 lifetime 86400

by: RishMasterPosted on 2008-03-22 at 12:11:41ID: 21187404

Sorry for not responding. They removed the PIX so I have to wait until we can go back out there to hook it back up. I will follow up as soon as this gets done and I test your configuration lines.

by: RishMasterPosted on 2008-07-17 at 17:16:42ID: 22031510

Still waiting on the client... Hope to have the PIX back online this month to complete the site-to-site... He's in the process of changing ISPs.
