Hi,
I investigated the external DHCP Client issue and found the reason for it.
It seems, that UMIP doesn't set the gateway in the created routing
tables (PBR), if an external DHCP Client is used.
Normally, the rule in a routing table (e.g table 20) looks like 'default
device wlan0 via Gateway ...', but if an external DHCP Client is used,
the rule looks like 'default device wlan0 ...'. So, the interface
doesn't know its gateway and produce and IPv4 ICMP error message.
I set the right rules manually and it works.
The question here is, does UMIP even know the gateway address because of
the external DHCP Client?
In the coming days, I will try to localize and fix it.
Regards,
Roland
