ASA5525-X IPsec VPN issue

[Timur Gubaev]

IPsec VPN configured between ASA5525-X and Linksys RV042

While transfering some exe from ASA5525-X side to Linksys RV042 side over VPN hash-sum of this file changes, so, when you open transferred file, you have an error message "File is corrupted". If you try to transfer file from Linksys side, hash-sum is ok.

Also, work with oracle application is interrupted because of unknown reason. IPsec works only if using router instead of ASA.

Files become corrupted only if they were transferred via VPN.

IPS is turned off. MTU and MSS changing doesn't bring expected results.

Hi Timur,

What kind of tranfer? FTP, TFTP...?

Is the specific inspection enabled?  (show run policy-map)

Thanks.

Portu.
