I see a compression setting on the RF660VPN and RF600VPN for the IPSec configurations. Is there a compression setting on the 5xx models? Should I turn on this compression? And if so, just 6xx-6xx, or also be turned on for 6xx-5xx connections?

- Ipsec Compression is only supported in the RF6xx products. There is no compression support in the RF5xx products.
- You can only turn on compression between RF6xx products, you can NOT use compression with RF5xx products.
