T1 on Balance 380

Product Discussion Peplink Balance
1

We have a Balance 380 connected to a Cisco 2800 router. The router has a serial T1 connection to it. The router can get to the internet fine, IP and DNS, however the Peplink cant get to the internet through the Cisco router.

We have a single route command on the on Cisco like this ip route 0.0.0.0 0.0.0.0 s0/0/0.500 (which is the serial interface for the T1). Any suggestions on making this work with the Peplink?

Hi,

Look like you have connection below:-

(LAN) B380 (WAN) —Segment A—> Cisco 2800 (T1) —> Internet

  1. May I know what are the IPs for B380’s WAN and Cisco router in segment A?

  2. B380 able to ping Cisco IP in segment A? You may ping via System > Ping.

  3. B380 able to ping to 8.8.8.8? You may ping via System > Ping.

  4. B380 is running in NAT mode?

Hi,

Look like traffic was stop at Cisco router. s0/0/0.500 (Cisco T1) is using public IP? If yes, have you configure NAT on Cisco router?
