Wondered if I could use your knowledge.
Currently I have all my site-to-site VPN's and Cisco Client VPN's coming into a Cisco Concentrator. But now I have these ASA's I want to start moving all this over from the Concentrator.
I have managed to move the Cisco Client users over, but I am having a little trouble with a site-to-site. It only a test at the moment but I wondered if you can see what I need to add.
Here is the setup:
| +-----------+ /-^-^-^-^--\ +-----------+ |
|-----| London |=====| Internet |======| Remote |--------|
| LAN+-----------+Ext \--v-v-v-v-/ Ext+-----------+LAN |
--| 192.168.21.0 22.214.171.124 126.96.36.199 172.19.15.0 |--
| 192.168.20.0 |
The IKE Phase 1 parameters used are:
* Main mode
* DH Group 5
* pre-shared secret of "123456789"
* SA lifetime of 28800 seconds (eight hours) with no kbytes rekeying
The IKE Phase 2 parameters used are:
* DH Group 5
* Perfect forward secrecy for rekeying
* SA lifetime of 3600 seconds (one hour) with no kbytes rekeying
Trusted networks in London are 192.168.21.0/24 and 192.168.20.0/24 (known as London_VPN_Subnets) and at the remote site are 172.19.15.0/24
The firewalls outside is 100.x.x.66 and the Internet router is 100.x.x.65
I have added the following to the config:
access-list inside_outbound_nat0_acl extended permit ip object-group London_VPN_Subnets 172.19.15.0 255.255.255.0
sysopt noproxyarp inside

nat (inside) 1 0.0.0.0 0.0.0.0
route outside 0.0.0.0 0.0.0.0 18.104.22.168
What am I missing, it's seems I need a route to contact this remote network, plus some access lists, any ideas?
I don't want any/many ACE's as these create 2 undirectional IPSec SA's, using host-based ACE's are not recommend as these use resources.
Many thanks if you get a chance
