Hi,

As far as i know you can't use layer 2 ip address (host IP) when routing 
features is in use, so the management address should be an interface vlan 
instead of the "set ip address".

Can you try it ?

Hey there,

we have always had routing problems when traffic is destined for the host 
address. Now I would like to clean up this mess once and for all.

>From the G3 release notes I see:
The G3 only supports one default route. If a default route is configured on the 
router, it will take precedence over the default route configured for the host 
IP. "Works as designed" is mentioned.
However, on N7 you can have two different default routes and it seems to work 
nevertheless. Does the N7 not work as designed?

Also, I see a bug (apparently fixed a long time ago) Changes and Enhancements 
in 1.02.00.0043
11085 Corrected an issue where management packets destined to the switch host 
IP address received on a routed interface, were replied to using the IP address 
of the routed interface

Now, is this still a bug or am I configuring sth wrong?

Here's the interesting part of the config (G3):

# Firmware Revision:  06.42.01.0046
!
#ip
set ip address 192.168.XX.207 mask 255.255.255.0 gateway 192.168.XX.251 ...
#Router Configuration
router
enable
configure
ip route 0.0.0.0 0.0.0.0 192.168.YY.251
!
interface vlan 30
...
interface vlan 130
...

->show ip route
Gateway                       Flags    Use   If    Metric
0.0.0.0/0                     192.168.YY.251               UG      
32304315rt1    5
->router>show ip route
*    0.0.0.0/0 [1/0] via 192.168.YY.251, Vlan 30

Now everything sent to 192.168.XX.207 gets replied to with source ip from vlan 
30 (not the host IP) and sent to gateway 192.168.YY.251 (not the host's 
gateway). Obviously, firewalls don't like that.

How to remedy? What is the best practice?

Thanks

Tom
