[rbak-nsp] NAT configuration

[Piotrek S.]

Hi,

Can anyone tell me how can i configure NAT many to many ?

Currently i have:

ip nat pool pool-NAT-customers napt multibind
address xxx.xxx.xxx.xx1/32 port-block 15 to 15
address xxx.xxx.xxx.xx2/32 port-block 15 to 15
address xxx.xxx.xxx.xx3/32 port-block 15 to 15
address xxx.xxx.xxx.xx4/32 port-block 15 to 15
...
address xxx.xxx.xxx.x49/32 port-block 15 to 15

nat policy pol1
! Default class
  ignore
  icmp-notification
! Named classes
  access-group NAT-ACL
   class NONAT
    ignore
    icmp-notification
   class cls-NAT-1-26
    pool pool-NAT-customers BRAS
    timeout tcp 18000
    timeout udp 60
    timeout fin-reset 60
    timeout icmp 30
    timeout syn 60
    admission-control tcp
    admission-control udp
    admission-control icmp
    endpoint-independent filtering udp
    no icmp-notification
!

Why many established connections are dropped (like SSH, HTTPS sessions,
etc.) after short period of idle time even though tcp timeout is set to
18000 ?

Thanks for help.

Regards
