Hi,

On 7150 NAT capabilities.

Can you please elaborate on ALG’s supported, which all ALG’s are supported.

How many active NAT sessions can be handled.

Thanks,

Hi Naveen,

In addition to your other question on ALG / NAT-Traversal (no), I hereby details on the amount of sessions.
Like ACL filtering, QoS, and other features, NAT rely on matching traffic : ACLs used for this are stored in TCAM, and complex NAT rules employing complex ACL would consume more TCAM space.
In general terms, There can be few thousands static NAT entries, many thousands dynamic entries.

Regards,
