Trying to figure out if you can host a Linux OS on a Cisco Router. Cisco config’s usually doesn’t take up that much space in memory and I’m trying to find out if anyone has tried to place a small version on the Linux Operation System on a Cisco Router. If so, were you successful? How can this be done? Thanks so much

Please let me know how to create a site to site tunnel between CISCO ASA 5520 and LINUX DEBIAN
using a pre shared key.
Cisco ASA is already configured and sent me these details.

Phase1 Key Exchange: 3DES, Data integrity: SHA, DH Group2

Phase2 Encryption: 3DES, Data integrity: SHA, DH Group 2

Perfect Forward Secrecy.

To be used as stand alone firewall. Kind of low cost substitute of Cisco PIX or Checkpoint firewall.
