There is a default route defined in TMM. The issue looks to be that when executing RESOLV or NAME without specifying a DNS server, it goes nowhere. I thought it would have used the DNS servers defined on the TMM. Was this a false assumption?

 

When I specify a DNS, it resolves correctly: [RESOLV::lookup @xxx.xxx.xxx.xxx -ptr [IP::client_addr]], which brings up a whole other issue. I'm going to have to define a pool of DNS servers to do the lookups against to provide the redundancy I need (not a big deal really).
