NAT port translation (overload) issues with Lotus Notes traffic

Hi Guys,

I need some help to understand & fix a Lotus Notes replication failure but
not always. I suspect my PAT has some issues.
Lotus notes server on WAN side & clients on FastEthernet0/0 (user LAN).

I have this below NAT/PAT setup with overload (Port translation). I need to
fine tune timers involved in TCP port translation timers. The below output
of "sho ip nat translations verbose" shows timer of 24hrs.

1. Do I have to still use "ip nat translation port-timeout tcp 1352 xx" to
set the PAT (TCP port translation) timers?
2. Has anybody experience PAT issues with Lotus Notes? Any fix?

I also noticed two timeout values does not seems right.
