Re: Issue with replacing SonicWall VPN with Cisco ASA VPN devices

For clarification, are there clients connecting to the 5505's, or is it just a site-to-site setup? In any case, what you want to do should be possible. When you define the ACL for what traffic goes down the tunnel from the branch to the hub, simply do "permit ip <LAN network address> <LAN netmask> any". Reverse this on the hub. I'm stumped as to why they think this is a security issue. Maybe TAC didn't understand what you want to do (or maybe I don't).

Hello Wizards, Our network team is replacing the client's SonicWall devices with Cisco ASA 5505 (remote office) and 5520 (HQ) devices. The SonicWall devices were basically used as VPN endpoints in remote offices to be concentrated back to the corporate HQ. All traffic not destined for the local LAN in the remote offices was sent to the corporate office via the "Route all traffic through this SA" functionality in the SonicWall. This worked well for the environment, but now there is the need to replace these devices, and Cisco ASA devices have been chosen. They are now trying to duplicate that functionality via the Cisco devices, but in talking with Cisco TAC, they say such a configuration is not possible, and even if it were, it would not be a security best practice. Implementation of the Cisco device has broken all Internet connectivity from the remote offices, since the only traffic allowed out to/from the Internet is through HQ (with the exception of the site to site VPN traffic to allow connectivity between remote offices and HQ). Remote offices can see everything on the HQ LAN, because the Cisco device is configured with IP information that allows it to route traffic to HQ. I can see some of Cisco's arguments regarding it not being a security best practice, but in the scenario of centralized management and monitoring of Internet-bound traffic, has anyone successfully configured the Cisco devices to mimic the "Route all traffic through this SA" functionality present in the SonicWall devices? I understand they could open up the Cisco devices to allow traffic out from each office, but that would require monitoring every remote office, and deviates from the centralized monitoring/management path we are currently traversing. I haven't personally been involved in this implementation, but was approached by the network team due to my security background, so I can get more details from the network team if necessary. We are simply trying to mimic in the Cisco devices the "Route all traffic through this SA" functionality present in the SonicWall devices. Thoughts?
