cannot ping from subnet A to subnet B for a specific host

[soup_or_power]

Hi
I cannot ping 192.168.5.149 from 192.168.11.65 and vice-versa.
The gateway for 192.168.5.149 is 192.168.5.1 and for 192.168.11.65 the
gateway is 192.168.11.253

Here is the router config

I'd appreciate if you can kindly explain to me the router config.

Thanks

It appears that whoever set up the router config wanted only one-way
initialized communication between the .11 and the .5 networks. The router's
interface on the 192.168.11.0 network is configured as a source NAT
Interface, and the Interface on the .5 network as the destination NAT
interface. Hosts 192.168.11.13, 58, 61 & 63 are statically mapped to the
same Host ID on the 192.168.5.0 network for some reason. With NAT,
connections have to be initiated from the source side. This appears to be a
Cisco configuration so I'm not sure whether the router will route packets
directly between interfaces that have been configured for NAT, but it
doesn't seem likely. Check the default gateway on the 192.168.11.65 computer
and see if it points to .1 If so, pointing it to .253 should fix it. Beyond
that, more info on the network would be required. Google for "Cisco NAT
configuration example" or "Cisco NAT tutorial" and see if you can get the
specifics.
