We set up a branch office VPN tunnel today. Traffic flows fine, and we can ping and access most nodes between the offices. However, two printers, an HP 4200N and a Kyocera TASKalfa 520i cannot be pinged or connected to over the VPN. On the LAN the two printers are fully accessible. On the opposite side of the VPN, the firewall can't even ping the printer IP addresses either. Anyone know why these printers might block or drop traffic coming from the VPN?
