So, when you do a ping from your host 172.24.50.3 to 1.1.1.x you will
probably see the counter increase for your rule (with restricted
destination).
Do "iptables -vnL FORWARD" to check.

That rule is not the problem.

What traffic are you sending that times out?
source ip, source port, destination ip, dest port, protocol?

Your forward and postrouting rules look fine and should work

My principal problems are with http, https and ssh. For example with a
https connection:

Chain FORWARD (policy DROP 48 packets, 2432 bytes)
pkts bytes target prot opt in out source
destination
4628 1901K ACCEPT all -- * * 0.0.0.0/0
0.0.0.0/0 state RELATED,ESTABLISHED
12 746 ACCEPT all -- * * 172.24.50.3
10.196.0.0/16 state NEW
42 2184 ACCEPT tcp -- * * 172.24.50.3
195.76.69.66 tcp multiport dports 80,443 state NEW
1 52 ACCEPT tcp -- * * 172.24.50.3
195.76.69.69 tcp dpt:443 state NEW
48 2432 LOG all -- * * 0.0.0.0/0
0.0.0.0/0 LOG flags 0 level 4 prefix `IPT FORWARD packet
died: '

First packets goes well, but after few seconds all goes to "IPT
FORWARD .." chain ...
So stuff is logged! Please show what is logged, cause that is the key!

Ok, I have found the problem. Exists an intermediate fw blocking this type of traffic ...

Sorry for the noise.

 .. and many thanks for your help.
