Hmmm.

O.K.  Can/should the ip address on my end be the same, too?

For example, consider a system as follows:

AMPRnet address 44.44.44.44

There are three axudp interfaces (amongst others).  
The first interface connects to AA1BBS-1 at IP address 11.11.11.11.
The second interface connects to AA2BBS-2 at IP address 22.22.22.22.
The third interface connects to AA3BBS-3 at IP address 33.33.33.33.

I want to use UDP port 10093.  So does AA1BBS and AA2BBS.  AA3BBS wants to
use UDP port 12345.

Would this configuration be correct?  If not, will you please correct it?


ip address 44.44.44.44

attach axudp pAA1BBS 256 11.11.11.11  aa1bba-1  10093  10093 
ifconfig pAA1BBS ipaddress 44.44.44.44

attach axudp pAA2BBS 256 22.22.22.22  aa2bbs-2  10093  10093 
ifconfig pAA2BBS ipaddress 44.44.44.44

attach axudp pAA3BBS 256 33.33.33.33  aa3bbs-3  10093  12345 
ifconfig pAA3BBS ipaddress 44.44.44.44


Thanks,
Michael

Michael,

No.

Each *interface* has a different source ip address, so when JNOS get's a a
possible axudp/axip packet, it loops through it's list of interfaces to see
which one matches the source ip address.
