TL-R470 not routing with a LAN side Juniper router
Region : UnitedStates
Model : TL-R470T+
Hardware Version : V2
Firmware Version : 5.1.0 Build 20120510 Rel.58982s
ISP : Comcast
I have a TL-R470 up and running. Internet access works fine if I connect a client directly to the TL-R470.
However, when I put a Juniper router between the TL-R470 and the PC then packets do not flow to the PC. Here is an outline of the network:
Comcast <---> TL-R470 <---DMZ---> Juniper Router <---internal network---> PC
DMZ = 172.31.0.0/24, TL-R470 LAN address is 172.31.0.250, Juniper address is 172.31.0.1 (ge-0/0/1)
Internal = 10.3.53.0/24, Juniper address is 10.3.53.1 (ge-0/0/0), PC address is anything on 10.3.53.0/24
A static route is in TL-R470, which is:
10.3.53.0 255.255.255.0 172.31.0.1 LAN 0 Active
A static default route is in the Juniper to send all traffic to 172.31.0.250.
routing-options {
static {
route 0.0.0.0/0 {
next-hop 172.31.0.250;
retain;
}
}
}
I have watched (via Wireshark) the packets on both sides of the TL-R470 and connections/packets initiated from the internal network are not processed. They are not sent on to the Internet (Comcast) by the TL-R470. I have verified they are being sent to TL-R470 but they seem to be ignored.
I have turned off "Enable ARP Spoofing Defense" to make sure the TL-R470 is not limiting packets since all the packets to the TL-R470 will have the same MAC (juniper) but will have different IPs (of the clients on the internet network).
Lastly, I have verified this works fine when a different broadband router or linux router is used.
Any suggestions is greatly appreciated!!
