AR 150 traffic drooped on pptp connection

hi all

I have bought your router AR150, firmware 3.024
AR150 is connected to a 4G router with firewall open

schema of my test as below:

MAC - IP → AR150, | virtual IP | WAN ip → 4G router → WEB

ROUTER ← PPTP server virtual ip

I have setup connection via VPN to my pptp server successfully in luci mode.
connection is working:

Protocol: PPtP
Uptime: 1h 30m 14s
MAC-Address: 00:00:00:00:00:00
RX: 1.23 MB (3657 Pkts.)
TX: 2.33 MB (4394 Pkts.)

Firewall is set

I can see in remote router connection is established

I can ping the remote router of VPN

$ ping
PING ( 56 data bytes
64 bytes from icmp_seq=0 ttl=62 time=70.550 ms
64 bytes from icmp_seq=1 ttl=62 time=71.091 ms
64 bytes from icmp_seq=2 ttl=62 time=70.465 ms
64 bytes from icmp_seq=3 ttl=62 time=63.931 ms
— ping statistics —
4 packets transmitted, 4 packets received, 0.0% packet loss

but all traffic seems dropped bt AR150 router.
if I made a traceroute to or a nslookup:

$ nslookup
;; connection timed out; no servers could be reached

$ traceroute
traceroute: unknown host

if I use the ip of

$ traceroute
traceroute to (, 64 hops max, 52 byte packets
 1 (  1.010 ms  0.891 ms  0.505 ms
 2 (  0.652 ms  0.936 ms  0.559 ms

but if I connect via client installed on my MAC, using same router 4G, I can connect to VPN server without problem.

so seems AR150 block traffic and doesn’t forward to VPN

any idea?

I have replied to you by email.

Hey @jasth and @luochongjun

I’ve got exactly the same issue! Were you able to resolve this guys? Thanks
