ping across routed subnets

Hi

I hope someone can help.
I've got an Endian (Community) box acting as a gateway/router on my network.
We have another MPLS router that connects to other remote sites on the LAN side.
The routing sort of goes like this

192.168.1.0/24 ---> Switch ---> 192.168.1.253 (Endian) ----> Internet
                                            ---> 192.168.1.254 (MPLS)   ----> 192.168.0.0/24

The endian has a route telling it that traffic for 192.168.0/24 goes out through 192.168.1.254 (MPLS)

This all works fine, SMB, DNS, RDP everything works fine, we replaced a Sonicwall with the Endian that had the same routes and it's just the same.
Except.......

I can't ping back to 192.168.1.0/24 from 192.168.0.0/24

It's a bit of a pain in the a**

Anyone got any ideas? I'm thinking of buying the hardware appliance so I was wondering if anyones seen this happen there also?

Thanks in advance,

Dave
