Cannot Ping Gateway from VLAN Bridge

Wed Jan 25, 2017 5:02 am

The Gist, Cannot Ping the Gateway from the VLAN Bridge on Router #2,

Router #1 Has two DHCP servers one on master port ether#2 and the other DHCP server is on VLAN 447
Router #2 can ping the gateway 100.64.10.1 from ether#24 but cannot ping the gateway from Bridge1. Bridge1 can pass traffic to where a computer plugged into ether#5 can receive a IP address but the PC cannot ping, winbox will even show both RBs in the neighbors list but I cannot pass a ping.

Thanks,

Config Router #1

I think you should have a ARP problem

Repeat the ping meawhile you are checking routers ARP table.
