How can I get the 10.11.12.x traffic received on tun1 at server B to 
eth2, and 172.16.1.x to eth1? 


I have a server A that sends 172.16.1.x and 10.11.12.x traffic via a 
gretab tunnel 192.168.1.x to server B.

            +-------------+                             +------------+
 172.16.1.x |      B      |                             |      A     |
     -------|eth1         |         192.168.1.x GRETAP  |            |
            |         tun1|-----------------------------|tun1        |
 10.11.12.x |             |                             |            |
     -------|eth2         |                             |            |
            +-------------+                             +------------+

When I put the tun1 interface of server B in a bridge with eth1 I am 
able to ping several 172.16.1.x ip's from server A. And communication on 

this network seems to be ok


- I cannot put eth2 on the same bridge. 
- I thought of creating a 2nd gretab tunnel and use each tunnel for a 
network, but I think there is probably a better solution.
