Hi!

How I can allow traffic between different vpns in cisco Asa 5505?

The vpns are lan to lan...

is possible?

I need than an user in site A 192.168.3.1  can ping to user B in 192.168.9.0

User A is in VPN "VPN-1" and user B is in VPN "VPN-2"

thanks

Hi,

Yes, you can merge the traffic from one tunnel into another tunnel.

You do this, by including the interesting traffic of one tunnel into the interesting traffic of the other tunnel and vice versa.

You can post the relevant part of the configurations to help you out.

Federico.

Hi,

sh run nat
sh run global
sh run static
sh run access-list
sh run access-group
sh run cry isa
sh run cry ipsec
sh run tunnel-group
sh run cry map
sh ip
sh run same
sh run management

sh run route

Or you might as well, post the ''sh run'' ;-)

Please specify the IP sheme on both sides.

Federico.

So,


The 192.168.3.0 is through peer 88.2.205.108
The 192.168.5.0 is through peer 0.0.0.218???

I think you have that IP wrong correct?

So,

You want to communicate from 192.168.9.3 (DMZ) to 192.168.5.249 (through peer 88.2.205.108), correct?


According to the configuration, 192.168.9.3 is via the DMZ interface (not through a VPN tunnel through the DMZ)
In other words, the ASA has no VPN tunnel to communicate with 192.168.9.x

If the configuration is just to the host through the DMZ, you should include it in the interesting traffic.
If you're going to access 192.168.9.x through a tunnel, please specify.

Federico.

Yes, the ASA has no VPN tunnel to communicate with 192.168.90

The configuration is for all the host in DMZ.

You don't have a crypto map for that peer (8.22.225.218), or you must correct the

current crypto map, to reflect the new IP (as well with the tunnel-group)

Then, check if that particular tunnel comes up and pass traffic.

You want communication from 192.168.9.3 DMZ to 192.168.5.249 through peer 8.22.225.218

This will be using ACL outside_2_cryptomap


So, you should include in that ACL:


access-list outside_2_cryptomap extended permit ip 192.168.9.0 255.255.255.0 192.168.5.0 255.255.255.0

And also,

access-list dmz_nat0_outbound permit ip 192.168.9.0 255.255.255.0 192.168.5.0 255.255.255.0
nat (dmz) 0 access-list dmz_nat0_outbound
