1) Your router isn't set as the default gateway.
2) Your router's routing table is messed up.
3) You've got your network all messed up (example, you're trying to route to/from a 83.161.118.x/24 subnet to your 83.161.118.XXX/28 address)
If your problem is #1 then you need to set your router as the default gateway and it *should* fix your problem.
If your problem is #2, then you need to fix the routing table to have your local subnet routed to the internal port and everything else routed to the external port (and whatever the IP address of what it's connected to).
If your problem is #3, then you need to fix your 2 subnets. It sounds like you've got a Class A overall (or are part of a Class A), you need to make sure that whatever you're connected to on the other side has it's routing tables and subnet correct or it won't be able to connect to you. If you're talking from a 83.161.118.XXX/28 network to a 83.161.118.XXX/24 network then what you're running into is that the /24 side won't route to you because they think your addresses are on the LAN (no need to route anything on a LAN). I'm not a router guru though, there might be ways to set this up on your router so that it will route, though I'm not thinking that's the case, as I don't think that a client tries to go to the default gateway unless something isn't on the local subnet.
As others alluded, it could also be a proxy/firewall issue. If your firewall and/or proxy are set to block ping/tracert, then you won't see it. If you don't have the ACLs set right, you won't get in or out (possibly). If you're going from a trusted network to a trusted network, then you need to make sure you've got everything setup appropriately. If you're not, it may be that you need to set up a DMZ (where your proxy/firewall go usually and maybe a web/e-mail server) and then setup certain protocols to pass to other addresses.
If all of these addresses are config'd on your side (you own the 83.x.x.x A class), then I'd bet that it's either #2 or #3. If you got your /28 subnet from an ISP, then I'd bet the problem is at your firewall/router (#1 or bad/missing ACLs on your proxy/firewall).

There is a router: funkwerk bintec r1200.
All proper configured through a external company.
What do you mean with layer 3 domains?

Well you need a router to cross subnets ... routers connect layer 3
domains.
I'm not sure if you're expecting this to be classfully routed or
something ... the Internet hasn't worked that way for a very long time.
Thanks,
