[lwip-users] Default Gateway does not change back after PPP link is deactivated

[Marco Jakobs]

Dear all,

i'm facing a problem with LwIP (1.3.2) and the use of PPP.

The Ethernet port has defined an IP address, Netmask and the default 
gateway configuration. Everything works pretty well, also sending 
packets to different subnets to the default gateway.

As soon as i activate the PPP link, the default gateway is now 
automatically the PPP destination, so the PPP overrides the default 
gateway (which is correct so far).

But after deactivating the PPP, the standard gateway of LwIP seems not 
to return to the value defined in the ethernet link! As soon as the PPP 
was up once and was put down again, the standard gateway is not working 
and all connections to different subnets are without any efford.

How can i "reset" the standard gateway of LwIP to the gateway already 
defined in the ethernet settings?
