   around strtoul). There is nowhere that isNumber_u* is called without it being
   immediately followed by a strtoul, outside of utils.cc.
 
-* Investigate and fix a bug: nsi_pcap_linktype(), nping.cc:1717, returns 
-  something different than DLT_EN10MB when sending UDP packets with the same
-  source and destination port number. If(dport==sport) it breaks; 
-  This happens also in TCP mode, and even in ICMP mode. This is weird. It might 
-  have something to do with the BPF filter. Some examples:

+* In some cases, when using nping through a VPN connection, nsi_pcap_linktype()
+  returns something different to DLT_EN10MB, and Nping fatals. Investigate
+  why this happens to nping and is not a problem for Nmap. Also, determine
+  why this doesn't happen all the time. What does it change between these
+  two?: sudo nping --udp 1.1.1.1 -g 999 -p998
+        sudo nping --udp 1.1.1.1 -g 999 -p999
+  The first one works, and the other one fatals with the "Currently only
+  Ethernet is supported." (error message @ nping.cc:1717).
