EX2700 strange routing issue

[tpham3783]

Hi,

I have a problem that was original posted on ubiquiti's support website at the link below.  Basically, when the EX2700 is configured in bridge mode, it somehow doesn't behave like a layer-2 ethernet cable.  I would like to know if anyone has an explaination for this?  Does the bridge modify anything at layer-3 like TTL or TOS tags etc....  Thank you.
