Here you go.

R1#ping 10.2.3.5

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 10.2.3.5, timeout is 2 seconds:

Etc.

A search in Google brought me this link to some unknown mailing list
with wannabe CCIEs ;)

Still doesn't really explain why is has this behaviour and if its
normal.

Hello Danny, Please can you send us the debug frame-relay packet output

Thanks

True. :)

I also could have mentioned that when using FR the default-gateway
command didn't work. Better said, it would probably work if only I could
ping the gateway. Seems to be an encapsulation problem.

R1:
interface Serial0
 description FR-switch DCE
 bandwidth 64
 ip address 10.2.3.1 255.255.255.0
 encapsulation frame-relay
 no fair-queue
 clockrate 4000000
 cdp enable
 frame-relay interface-dlci 115

R1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R1(config)#no ip routing
R1(config)#ip default-gateway 10.2.3.5
R1(config)#exit
R1#ping 10.2.3.5

Type escape sequence to abort.

To be honest, I don't know why it does that.
