Am I the only one who still has his WRT54G v2 in full service? Its no longer a router, just an wireless access point and it runs dd-wrt. Nevertheless, it is probably the only 9 year old device still in active duty without any problems.
Up until 2008 or thereabouts when I upgraded from DSL to FiOS and 10Mbps ethernet became a bottleneck, my home firewall was running on a Sun SPARCstation LX c.1992. Never gave me any problems and it was probably 16 years old when I retired it. Haven't powered it up since then but I suspect it would still run.
Worst case, setup your stateside box to sit on port 80, which is NEVER entirely blocked.
May not be blocked from the far side but if you happen to have Verizon as your ISP, they have been blocking port 80 from getting to your stateside box for years, purportedly as an anti-spam mechanism. 443 goes through ok as does 8080. Good luck and stay safe.
