3G Modem connected but...


#1

Hi,

I have a VyOS VM and I have successfully connected a Huawei 3G USB modem. I have internet connection working from VyOS. DNS is pulled by mISP. I believe it has set a prober route?:

S>* 0.0.0.0/0 [1/0] is directly connected, wlm0 C>* 10.64.64.64/32 is directly connected, wlm0 C>* 127.0.0.0/8 is directly connected, lo C>* 192.168.0.0/24 is directly connected, eth1 C>* 192.168.1.0/24 is directly connected, eth0 C>* 192.168.2.0/24 is directly connected, eth2 C>* 192.168.31.0/24 is directly connected, eth0.31 C>* 192.168.100.0/24 is directly connected, eth0.100

However, my issue is, that none of the internal networks are can access the Internet with VyOS as router. The traffic is not routed or…

All outbound traffic is masqueraded.

Can someone guide me in troubleshooting this?

1st step: Is this a DNS or routing/NAT issue?
Test from client: ping 8.8.8.8

Hi there,

Thank you for helping out.

DNS works, but traffic is not. From client (My VyOS router is 192.168.1.201)

ping -a 8.8.8.8

Pinging google-public-dns-a.google.com [8.8.8.8] with 32 bytes of data:

If i disable the 3G modem wlm0 interface and enable the WAN connected port on eth1 everything works.
