VPN tunnel with no encryption

paulawong · ‎05-14-2003

Hi there,

Just wondering if it is possible to build a VPN tunnel from PIX to PIX without

any data encryption. This will help increate performance on the boxes, althought I do not understand that it will not secure the data.

Any help is greatly appreciated.

Thanks,

Paula

Hi Paula,

You can configure the pix to do null encryption. However, you have to use some authenticator like sha or md5. E.g.,

cry ipsec transform-set myset esp-null esp-sha-hmac

Hope that helps

Hi,

You can refer to the rfc - The NULL Encryption Algorithm and Its Use With IPsec for more Info on NULL Encr Algo.

Thanks,
