<p>Hi everyone,</p>
<p>I am having some trouble with routing data from an olsr network to a non-olsr network. In particular, UDP streams do not seem to get routed over multiple hops on the OLSR network. I would appreciate any help from the experts on this forum. Here is my network setup:</p>
<p>OLSR network:</p>
<p><a href="http://192.168.10.0/24" target="_blank">192.168.10.0/24</a></p>
<p>Non-OLSR network:</p>
<p><a href="http://192.168.1.0/24" target="_blank">192.168.1.0/24</a></p>
<p>Node A -> <br>
IF1: 192.168.10.5 (OLSR)</p>
<p>Node B -> <br>
IF1: 192.168.10.6 (OLSR)</p>
<p>Node C -> <br>
IF1: 192.168.10.7 (OLSR)<br>
IF2: 192.168.1.2 (non OLSR, on managed network but will always get 192.168.1.2 from dhcp on external host)</p>
<p>Node D -><br>
IF1: 192.168.1.1 (non OLSR)</p>
<p>Node C has the smart_gw plugin running and even sends out HNA messages saying it can route to the 192.168.1.0 network. I checked the routing table on A & B and they did indeed have one-hop routes inserted that would lead to the gateway. I was able ping the outside network from within the OLSR network over multiple hops. The outside host, node D, however is constrained to talk only to IF2 on node C, so I have an iptables rule on the gw to masquerade data coming in from the OLSR network to look like it is coming from IF2 on node C. This works too, since I have full connectivity to node D, when I run an application on node B, which is one hop away from the gateway, IF1, on node C. However, when I move node B out of range from the gw, i.e. node C, so that it is 2 hops away, which I confirmed from debug output from the txtinfo plugin, it is not able maintain connectivity (tcp and udp streams) with node D and my application on node B breaks down. Are there any settings I am forgetting, or is it that UDP data over OLSR is not a good idea. Thanks much and I appreciate your help in advance.<br>
