Hi,
I'm facing an unusual problem with routing. I can access an internal
server (with real IP) thru an OpenBSD gateway (gwA). Everything works
when connection is initiated from the Internet. But gwB can't make its
way back to the Internet.
Every attempt to access any host on the Internet gets to gwA
int_wireless, but doesn't goes out on ext_if. gwB can't even ping gwA
external address 1.2.3.2.
It makes no difference whether pf is enabled or not and, yes,
net.inet.ip.forward is enabled.
They're connected thru wireless bridges. I'll try to represent the
network below:
gwA has 3 interfaces: sis0 (external), vr0 (internal), and xl0 (int_wireless).
gwB has 2 interfaces: sis0 (ext_wireless), and rl0 (internal).
+-------+ +-----+
| gwB |sis0----<< RADIO BRIDGES >>----xl0| gwA |sis0-----<< INTERNET >>
+-------+ +-----+
gwB's
-----
gwB:24$ cat /etc/hostname.sis0
inet 10.10.10.250
255.255.255.0 NONE
inet alias 1.2.3.65 255.255.255.192 NONE
gwB:25$
gwA's
-----
gwA:511$ cat /etc/hostname.xl0
inet 10.10.10.254 255.255.255.0 NONE
!/sbin/route add -net 1.2.3.64/26 10.10.10.250
gwA:512$ cat /etc/hostname.sis0
inet 1.2.3.2 255.255.255.192 NONE
gwA:513$
gwA:514$ sysctl -a net.inet.ip.forwarding
net.inet.ip.forwarding=1
Has anyone a clue ?
TIA,
