Hello,
I have a network setup that works perfectly fine under Linux 2.2.17 (and
other OS's) but not under 2.4.0-test9. Here is the setup:
NAT/FW
router | router
host A <----X------>W--------Y------> host B
1.1.1.1 ^--------Z------< 2.2.2.2
[1.1.1.1 <-> 1.1.9.9]
Host A is behind a NAT firewall and has address 1.1.1.1
Host B on the other side has an asymmetric route to/from host A.
The FW translates A's 1.1.1.1 address to/from 1.1.9.9.
The FW allows unrestricted access from the outside to host A's SMTP port.
I have no problems with connections initiated by host A to host B.
Telnet, SMTP, ssh, etc all work fine, so the routing is set up properly.
I can ping host A from host B, as the FW rules allow it.
I cannot, however, connect to host A's SMTP port from host B.
The problem is definitely with host B and with Linux 2.4.0-test9. The same
host running 2.2.17 works fine.
Any ideas what's going on?
