In addition to the stuff the FAQs ask for, please tell us what OSs the systems at 10.18.0.26 and (especially) 192.168.0.11 run ... in particular, do you KNOW (based on an actual test) that the system at 192.168.0.11 will itself respond to pings?
Also, can each system ping its "local" interface address on the LEAF router? What about the other address on the LEAF router?
I'm a bit uncertain as to what you mean by "transparent proxy"; the term, in my limited experience, applies to a (Web, usually) proxy server that the clients do not need special configuration to use, but I'm doubtful that this is what you mean. Do you just mean an ordinary (non-NAT'ing) router? Or does the LEAF router need to do proxy arp on both interfaces? If the latter, is it possible that you've configured it to proxy arp one network but not the other?
And just in case we're missing something "obvious", it would be wise to include ALL the basic information the SR FAQ asks for in your follow-up.
