The operational complexity of running two NATs, from two different vendors, is very high: different CLIs, different alarming/alerting (e.g., SYSLOG, SNMP, per-session NAT logging), different features (e.g., IPsec Passthru, SCTP), different implementation of features (e.g., TCP MSS adjustment, fragmentation [timeouts? how much memory dedicated to reassembly? out-of-order packets supported?]), bandwidth and throughput (Mbps, pps), make it too hard to operate both NATs. To my knowledge, sites do not run two different implementations of DNS servers (e.g., ISC BIND and InfoBlox, or Microsoft and Unbound) where both DNSs back up each other. Like NAT, DNS needs to be rock-solid reliable, and a single packet could take out a DNS server. -d
