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 192.168.8.10 → AR150, 192.168.8.1 | virtual IP 10.0.0.2 | WAN ip 192.168.1.2 → 4G router 192.168.1.1 → WEB

ROUTER ← PPTP server virtual ip 10.0.0.1

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.)
IPv4: 10.0.0.2/32

Firewall is set

I can see in remote router connection is established

I can ping the remote router of VPN

$ ping 10.0.0.1
PING 10.0.0.1 (10.0.0.1): 56 data bytes
64 bytes from 10.0.0.1: icmp_seq=0 ttl=62 time=70.550 ms
64 bytes from 10.0.0.1: icmp_seq=1 ttl=62 time=71.091 ms
64 bytes from 10.0.0.1: icmp_seq=2 ttl=62 time=70.465 ms

^C
— 10.0.0.1 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 myip.com or a nslookup:

$ nslookup myip.com
;; connection timed out; no servers could be reached

$ traceroute  myip.com
traceroute: unknown host myip.com

if I use the ip of myip.com:

$ traceroute 104.31.66.68
traceroute to 104.31.66.68 (104.31.66.68), 64 hops max, 52 byte packets
 1  192.168.8.1 (192.168.8.1)  1.010 ms  0.891 ms  0.505 ms
 2  192.168.8.1 (192.168.8.1)  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
