WARNING: 8e6 recommends contacting one of our solutions
engineers if you need assistance with router mode setup proce-
dures.
Firewall Mode
The firewall mode is a modification of the router mode. With
the R3000 set up in this mode, the unit will filter all requests.
If the request is appropriate, the original packet will pass
unchanged. If the request is inappropriate, the original
packet will be blocked from being routed through.
Using the firewall mode, while the outgoing request is
delayed slightly—to allow filtering to take place before the
packet leaves the gateway router of the network—return
traffic remains unaffected.
