I'm going to set a IPSec tunnel between a Cisco Router (17xx) and an ASL 3.201, but as usual something goes wrong ...

... all seems going right, but when I start some traffic (ping) I recive : cannot respond to IPsec SA request because no connection is known for 80.18.204.198...80.18.204.196===0.0.0.0/0
... if some one could help !!
P.S. I think that an Astaro official and Tested document expalining cisco -> ASL sample connection could be usefull
Remove the Tunnelinterface , for the rest refer to the Astaro Sample Config to Cisco Router which works great. Dont forget to bind the Crypto map on the extrnal Interface.
I'm having trouble setting up a VPN between a Cisco (IOS 12.2.27b, Enterprise, IPSEC, 3DES) and an Astaro V5 firewall. The ISAKMP SA will not be established also I'm sure that the parameters are configured correctly.
I'd like to doublecheck thid with the PDF you've mentioned. However the docs page has moved and the knowledgebase returns an empty HTML document.
Is there another working pointer to the PDF or does someone have a local copy of it?

i can send you what worked 3,5 years or more ago here in my test....dunno anymore.
(Config+Screens)
Its IOS 12.2 and ASL 2.012 based...hehe, but should still work.
Maybe lifetimes etc or pfs must be modified nowadays.
Aswell there are much Openswan to Cisco IOS samples available on the net.
