Hi, using a Comel ER75i gprs router, I've seen PPP gateway is always 10.0.0.1; using RB411U with 3G MiniPCI-e card, PPP gateway is always 10.112.112.116.
Both with same ISP.
So, PPP gateway IP address depends from....... what?

I had to install GPRS modem as failover gateway, but both gateway IP address and gprs LAN address were 10.0.0.1.
I would like to avoid same trouble again.

Thanks.
