Does anyone know of any inherent problems/bugs in vanilla 4.2bsd
internetwork routing? Our machine has just been put on the ARPANET
via a 19.2K baud leased line to an imp off site (using an ACC HDH 
interface). We can't seem to connect to any site outside of the
ARPANET (i.e. any site that does not have an address of 10.?.?.?).
Every attempt times out. I realize there's the possibility of
the gateways being too loaded, but, I can get from another machine
that lies on another net (i.e. milnet) to our host without any
problems -- so it only effects outgoing attempts. Doing a netstat
shows that the state it's hung in is "SYN_SENT", and it seems to
never change that state. Doing a netstat -r shows that some attempt
has been made to connect on the gateway (there will be a number in
the "use" column for that gateway). 

Does anyone have any clue why this is happening? Are there any fixes
that can be obtained? This is a vanilla 4.2bsd system on a VAX 11/780.
We are planning an upgrade to 4.3bsd fairly soon, but not soon enough.
Any help would be greatly appreciated.... Thanks.
