Trying to configure pf to use round-robin outbound. Currently setup with two T1 gateways.
Works fine from the internel network, but I get this from the firewall -
Trying 2001:4f8:0:2::e... ftp: connect to address 2001:4f8:0:2::e: No route to host Trying 204.152.184.73... ftp: connect to address 204.152.184.73: No route to host Trying 62.243.72.50... ftp: connect: No route to host
Same thing for ssh
# ssh chinet.com ssh: connect to host chinet.com port 22: No route to host
Have some pretty basic rules just for testing, what am I missing ?
