RVS4000 and routing issue

Hello everybody.

I got an RVS4000 which on the WAN side has a modem with PPPoE dial-in. On the LAN side, I have a pool of public IPs. The first available IP is configured on the LAN interface (subnet /29), while the next one is configured on a Fortigate firewall interface. Now, I can't get reach the public IP on the Fortigate device, but from the Fortigate itself I am able to ping to the outside world (but no ping replies are finding their way back).

The routing table on the RVS4000 looks as follows:

Dest IP              Subnet Mask           Gateway     Interface

81.111.222.21    255.255.255.255     0.0.0.0           WAN

88.222.111.80    255.255.255.248     0.0.0.0            LAN

239.0.0.0           255.0.0.0                 0.0.0.0             LAN

0.0.0.0               0.0.0.0                     81.111.222.21 WAN

81.111.222.21 is the WAN IP on the RVS4000

88.222.111.80 is the network address of the public pool I got (.81 is the LAN IP of the RVS4000, .82 is the one on the Fortigate device)

I do not see why packets are not reaching the LAN-based device (Fortigate). Maybe I'm missing something very basic...

Could anybody give me a hint?

Thanks and kind regards,

F.

RVS4000 and routing issue

OK, sorry for bothering...

I managed to get help from this topic:

https://supportforums.cisco.com/thread/2022615

There it states that it should be put into "routing mode" for the purpose I want to use it for... and that solved my issue!

Thanks!

F.
