Net 2 Net fails on phase 2

Level 1

Tried so many things I'm completely lost now and need fresh eyes on the problem. I can post the ASA config and debug log. The other end device can't print out a config (custom Unix box) so ask questions if needed.

here is the relevant info.

No help here?

What is your Local LAN and the remote LAN subnets. I think, the Crypto ACL's are configured incorrectly. The source and destination are reversed.

access-list Outside_30_cryptomap extended permit ip host 192.168.5.0 10.0.0.0 255.0.0.0

Also, check the mask on the 192.168.5.0. Is this a host IP Address?

Make sure to make the changes to the NAT 0 command as well and try bringing up the tunnel.

I hope it helps.

Arul

Also can you check if ipsec transform sets are same on both the devices
