ASA 5505 VPN site-to-site 1

[VanZenden]

Hi all,

I've setup VPN (site to site) between to locations according to this document:

http://www.cisco.com/en/US/docs/security/asa/asa72/getting_started/asa5505/quick/guide/sitesite.html

and it doesn't work. Is VPN Wizard enough or I have add somethnig else in CLI, like additional access-list.

both locations have static WAN addresses.

 

[boymarty24]

The wizard works imo good. It should be enough. But there is alot of other things that can mess upp the tunnel. Are both firewalls cisco?

 

[unclerico]

Post your full scrubbed configs from both devices

I hate all Uppercase... I don't want my groups to seem angry at me all the time! =)

You have to define wich traffic the VPN should listen to. I can´t find that anywhere in your config.

One suggestion. The second ASA with DHCP on the outside interface. Why don´t you use the easy VPN on that asa instead? In such scenario you configure the asa as a vpn client, works great.

http://www.cisco.com/en/US/products/ps6120/products_configuration_example09186a00805c5ad9.shtml

 

[Supergrrover]

The ACL's are there; they just are not correct. Also as boymarty pointed out, you will need to use A as the easyvpn server. There is no way around it for the dynamic address.

Your site A nat0 and interesting traffic maps need to be exact mirror images on site B.

Site A
access-list siteB_vpn_traffic extended permit ip 192.168.4.0 255.255.255.0 192.168.8.0 255.255.255.0
access-list vpn_nat_exempt extended permit ip 192.168.4.0 255.255.255.0 192.168.8.0 255.255.255.0 - site B vpn
access-list vpn_nat_exempt extended permit ip 192.168.4.0 255.255.255.0 192.168.0.0 255.255.255.0 - RA vpn


Now for this -

crypto map map1 10 ipsec-isakmp dynamic map2
crypto map map1 20 match address 103
crypto map map1 20 set peer 193.xxx.xxx.50
crypto map map1 20 set transform-set trmset1
crypto map map1 40 match address outside_40_cryptomap
crypto map map1 40 set pfs
crypto map map1 40 set peer 213.xxx.xxx.210
crypto map map1 40 set transform-set ESP-DES-SHA

You will need to fix the crypto maps as well. The ACL should include the destination internal ip scheme not the external address. That's what the "set peer" statement is for. You will also want to change the order of the crypto map so that the dynamic is the last entry - the first policy that matches gets used adn you want yout L2Ls to always take precedence.

Really go through the link that Marty posted. That will get you up and running. My recommendation is to blow it all away and start over.

Hi, thanks for reply

Location B has static address. I know it doesn't like it

I'll try both scenarios, tnx again

 

[VanZenden]

I ment it doesn't look like it

 

[VanZenden]

boymarty24,

As you suggested I've setup ASA (at location B) as VPN Hardware Client - client mode, and it works

But I can't get it working as NEM (Network Extension Mode), because I'd like to use IP SoftPhone/IP Phone (Avaya - H.323) connected to Avaya PBX at location A, since Location A needs to see Location B subnet.

Am I missing something ?

Syslog messages when connected in NEM mode:

No need for NEM, when using IP SoftPhone (with VPN software Client) it worked without problems
